In what movie does a non-horsey father's mistaken bareback ride lead to the horse's trip to the Washington International Horse Show (I think, that's the jist I remember...it's old/obscure enough there isn't even a plot synopsis on IMDB!)
Radar gave him the horse, and the horse was Sophie. Hawkeye, BJ and Radar found her wounded. She was donated to an orphanage when the war ended. I remember the colic episode. Margaret had appendicitis in the same episode.
My trivia.. hmmm..
What was the name of the Grey carriage pony in the Black stallion?
