SAME EXACT THING HAPPENED TO ME (WELL, ALMOST.)
I am really bad at jumping. I have been jumping for about 2 yrs now and I'm still at 1 foot! I used to shareboard on a SEATTLE SLEW grandson (ex-racer who absolutley HATED racing but loved jumping and being a pet.) untill a change of barns (the whole family owned business re-located) I couldn't ride as often, other new and *scary* people rode him, etc. everything changed. The owners decided to sell him off to Iowa due to "saftey reasons" (he started to buck and rear and bolt and bite and kick a lot more than usual)
here is a picture of him.

His jockey reg. name is "I'm A Player" He was born in KY on May 6, 1999, and he is seal brown. His Sire is Fast Play(stud fee $5000, sone of the Seattle Slew) Dam: Leading Ballerina (by Moscow Ballet) Quite a royal pedegree there! and to think, my stable got him for free!
I really, truley know how you feel right now, deepest sympathy.
