What a great topic! One of the biggest blessings I've ever had was my childhood!
Growing up we helped a lot around the house and gardens, cutting lawns, babysitting, baling hay, tending animals, always stuff to do, but also biking miles and miles, sometimes 5 across the road holding hands and not the handle bars. We'd get old bike parts at the local dump and build or fix our own. We built clubhouses and tree houses, and race tracks. We planted and harvested our own "pickle patch" and sold them to a canning factory for cash. We read, read and read some more. Long games of monopoly, checkers, mousetrap, tinkertoys and erectorsets. We'd build whole villages with Lincoln logs. Wed line up hundreds of dominoes in intricate patterns and tgen watch them all fall. We'd use several decks of cards to build intricate houses of cards. We painted, built things, made things with modge podge and with paper mache. We made our own plays and sold tickets to audiences (sometimes the audience shifted as they were needed in a scene then sat back down). We made our own tvs out of cardboard boxes. We'd make our a big story, draw the pictures, tape the pages together in a long long scroll. Then we'd roll it up on a stick on each end and scroll it past the "screen" of our cardboard box, narrating the scenes as each picture scrolled past. We seemed to do the news most often. We'd build model cars and put bottle rockets in them to see how far down the road they'd go. We build two story matchbox car racetracks and shoot the cars off into oblivion. We'd play tag and hide and seek in cornfields, build clubhouses with trap doors in the hay bales, swing off the barn rafters and land in the chopped hay, and climb silos. We cat paths in the lawn with the mowers (or made patgs in the snow in winter) and then played games of tag in which you had to stay on the paths (i think we called it the gox and tge hound.) We played freeze tag. We swam, fished, canoed, slept in tents or out in the open in the back yard. We had tons of campfires with stories, songs, and roasted hotdogs and marshmallows. We played jarts, croquet, volleyball, badmitton, baseball, kick the can, flashlight tag, red rover, ghost in the graveyard, and many more.
We had 3 old big empty cable spools and had great fun with those. They were picnic tables, places to hide, and more. We'd roll them down hills while standing on top, trying to make it all the way down the hill without falling off (We were also very good at logrolling in the lake -we had great balance). We used to roll those spools up the road about 1/8 of a mile, crawl inside, and then roll 1/4 mile down the hill on the road if we were lucky enough to roll straight and not hit a ditch. We rollerskated and skateboarders and used pogo sticks. We taught the dog to pull us on skates and sleds. We jumped rope, ran everywhere, played on the swing set and climbed trees. We climbed everything! Any metal pole, trees, siloes, an area ski jump, fire towers, barn rafters, roofs... We were spies with little notebooks looking for clues, archaeologists digging up great treasures, cops ready to hand out tickets, indians, cowboys, circus clowns, acrobats, astronauts, and veterinarians. We build stick houses in which the outlines of our houses were made with sticks and stones. We built whole cities complete with roads, rivers and lakes in the huge sandbox in the yard. In the winter we flooded the end of the field and made our own hockey and skating rink. We played hockey with broom handles and sticks. We made forts and snowmen and snow angels. We went snowmobiling, and watched the northern lights. We watched the stars endlessly. We made our own snowshoes and skies. We went tobogganing and sledding and innertubing, often miles from the house for many hours at a time. We'd climb up in the old granary and climb out the window onto the roof so we could sled off of the metal roof, and fly off of the edge of tge roof. We went to see how maple syrup was harvested and put fresh maple syrup on fresh snow snowcones. We built connecting snow caves and long tunnels. We added water to the sledding hills to makes solid iced ramps and jumps. We climbed frozen waterfalls.
In the summer, we'd dress in all of our winter gear and pretend it was winter. We made forts out of blankets on the clotheslines. We used giant pieces of cardboard as our own "windsurfing" sails, and would let the wind push us all over the yard. We slid down hills in the summer in cardboard boxes. (We tried this on steps, but it didn't work so well!

) But we did pretend to be alligators and would go down the staircase on our bellies, headfirst, slowly letting ourselves down one step at a time by using our arms. We'd play in our rooms pretending the floor was water filled with sharks. We'd make our way around the room without touching the floor by swinging on the door (standing on the doorknobs), then stepping onto a dresser, jumping over to the top of the bunkbed, then jumping to the big bed, climbing over another dresser...
We'd go to the dump and watch bears come to get the food scraps the old man used to set out for them at the far back of the dump. We'd go out at night with spotlights to find huge groups of deer just to watch them. We'd sit on the garage roof to watch fireworks. We'd go see the Lake sturgeon when they went up the river to spawn, and we'd make the trip to an area west of the city to watch trumpeter swans and snow geese migrating.
Dad was GREAT about bringing us places to see how things were made or built. We went to mechanics and sawmills, potato warehouses and paper mills. We saw how toilet paper, paper towels,and school paper were all made. We watched candy being made and cigarettes. We climbed ski jumps and went to airports. We went to construction sites and gravel pits. We shook Mr. Wipples hand. We watched pencils being made and how dams worked. We toured sunbmarines, fire boats, WWII ships and airplanes. We went to museums of all kinds, mostly for free.
We built our own dams and fish beds, and watched beavers making their own. We caught, cleaned, and cooked our own fish. We made our own kites and then flew them. We mixed our own soap bubbles, carved things out of bars of soap and wood, and made our own candles. We built little boats and raced them in the creek. We made our own swings and hammocks. We brought home all kinds of strays. We'd go to waterfalls, go rockclimbing, and follow the creeks for miles to see where they went. We explored logging roads and back roads. We had two telephone poles tied together on one end. This was leaning out over the lake held by a cable. A rope hung from the top and was suspended over the water. Then we'd take the rope, climb a set of steps and swing out over the lake, flipping off of that rope into the deep water.
We did flips, stood on our heads, walked on our hands, did cartwheels and summersaults, and had "wheel barrow" races with human "wheelbarrows". We played dodgeball and didn't cry when we got hit. We had potato sack races. We caught and raced turtles. We caught and raised pigeons.
One spring our neighbors yard flooded. Their parents were both working (my mom was home so we could do this at our house...). We brought all of their (wood) dining room chairs outside, and set them in the water, then jumped from chair to chair to stay out of the water. We were having a fabulous time until their mom got home!
At some point, we acquired a really really heavy old barber chair. It was on our front porch for years. We had so much fun in that old chair giving each other "rides". One person would get in and the othervwould pump a handle to raise it up. Then we'd grab the foot rest and spin the chair around and around.
We made gilts out of boards and old metal coffee cans and would walk around the yard on our "stilts". We made astronauts suits (and forts) out of cardboard (and dress up of all kinds!). We'd make telephones out of string and tin cans. We made our own periscopes, and i even made my own camera when i was in 6th grade.
We played cops and robbers on our bikes.
We all went to the fair at the end of the summer and we all had lots of entries: animals of all kinds (horses meant you got to stay overnight at the fair, sleeping on bales of hay!!), photography, canning, knitting, crocheting, sewing, painting, produce, artwork, woodwork... animals got you free admission.
The thing is, we all worked too. But when we weren't doing chores of some kind, we were never bored. We were busy all the time. I could go on much longer on this topic. I had a fabulous childhood, and was very blessed to have the parents I did, the family I grew up in, and both the time and community I grew up in. God has been exceedingly good to me!!
Oh to be young again and to have that much energy!
