Arkansas looks gorgeous! I love the trees - reminds me alot of Oregon & Washington state and makes me think I should make it a point to see it one day.
What a cutie (your mini mule) I'm sorry about your hubby OUCH! The mule is probably frightened, and being a prey animal, it has a fight or flight instinct - so if it can't run away (that being it's first choice) it will naturally try to fight, and kicking, striking, and biting are it's only defenses. I hope you have someone knowledgeable at least with horses to help you with this one, as even tho it's small, it can be dangerous.

What a great wagon! It's probably a bit on the large side for the little mini mule, but wow - How cool to have one

It looks like it's in great condition too!
I bet you could find a small cart for your mini to pull, or if your hubby is handy, he could probably build one size appropriate for your little guy. I sure wish I could find a deal like that here - what fun!
eta: I hadn't read yet that you have experience - sorry!
