I got the ride on one of the barn owner's ex-racehorses as well. Zen is a seven year old Thoroughbred mare. I'm happy to pick up an extra ride on the weekends without the additional expenses. I did some round pen/groundwork with her today, and she was pretty good. She thought the whole thing was an "eat and run" buffet experiment (round pen is on grass), but other than the food distraction, she eventually caught on to what I was asking and came around. She should be fun to play with and is super cute and sweet.
