Hi, I am planning on showing my miniature pinto at the Pinto World next year, but I am not sure what to wear. I am going to enter the Open Halter Geldings, Miniature, 34 & Under, 3 & Over; the Youth Pleasure Driving, Pony/Mini/B Mini; the Open Trail-In-Hand, Miniature; and either the Open Hunter In-Hand, Miniature or the Open Jumping In-Hand, Miniature. Also, what is the difference between those two and how high are the jumps in those classes? Can you tell me what I should wear for each of those classes? Thanks!
