wow haha that took me...7 minutes to read. I wish I could do half the stuff you told me to, but I would only ride him in a lesson, and then my trainer is telling me what to do.
Casper wasn't scared. I wasn't sudden or anything when I took the crop, it was when I turned back around and was reaching for is eins again that he snapped at me.
He didn't buck as we were going into the canter...it was when we were cantering.
Yeah I can see a stride, but with him, he never EVER gets the correct amount of steps. In a 6 stride line, with his owner riding, he'll get 7 or 8 steps. When I rode him, I managed 6 one time.
There's a big chance I will be riding on friday this week...and I'm really worried about having to ride him.
I don't like the big mean bits either. I know one horse who seriously needed one though. His owner is at college, so he's been used as a school horse, and with every single rider who rode him, he ran away at the canter. My trainer got on him (when I rode him) and worked with him a bit, but he still ran away with the students. Now he just bucks, but i prefer that much more to him running away.

Thanks a lot! And I'm really hoping I never have to ride Casper. I'd rather ride IO, the spazziest horse EVER.
