Other than the occasional sitting on the neighbor's horse or trail ride, I got to do lessons and work at a horse rescue when I was...18. I acquired a mini at 23 and really got to own a real (well, she is kinda pony sized) horse at 25.
Kind of a late start compared to many of you! But I've been horse crazy for as long as I can remember. Rode Grandpa's cow Bossy as often as possible, trained my first dog to ground drive, "neck rein" (sorta) and pick up her feet like a horse and always read every horse book/magazine and watched every horse show/movie in sight.
