My second horse was also a tb. He was an 11, big chesnut with 2 hind socks. He was a thick 16'2hh.He was registered and had been owned a police officer. This horse was broke for pretty much anything. Anyone could get on him and we could do anything with him from trails, to showing to even vaulting or other stupid things kids do.
He was a very laid back horse tho when he wanted to he would use his size to be a jerk. If you didnt know him he would have scared you.
Great horse, a lot of fun to ride.
