Here is the video I promised.
He is going to kill himself on that thing! It is more than 3 feet off the ground...very dangerous. But he loves it of course. I have it hidden in my room with a blanket over it so he can't climb up it and ride a no handed rodeo when no one is looking. Horsey time requires serious supervision. That thing was a pain to put together also. You have to be a mechanic to be a parent.
He was also climbing all over it and stealing tools when I was putting it together...that didn't make it any easier. I was very impressed though with his hand/eye coordination when he stole the screwdriver and started to screw in the bolts that I already put up. He would put put the tip in the screw no problem.
