I’m a “pro” technically, in that when I first joined up with USEF and USDF I was teaching riding lessons part time (most of my income back then) while going through my last couple of years of college, on top of riding a few horses for other people on occasion. I haven’t given legit, paid lessons in about 5 or 6 years, but it’s such a pain to get my status changed that I just compete in Open when we do go to shows. I could worry about what others might think, me very clearly not a pro rider, on a super downhill little hony mare, sometimes in a jump saddle, being thrilled if we break 60. But tbh I don’t really care. We will never be competitive, at least in Open there are fewer riders in my area so we might get a ribbon if we are lucky for our efforts I just like having those as tangible memoirs of our little accomplishments, even if it’s like 6th out of 7 or something.
Honestly, the only reason I’d want to do Amateur is because AAs have some fun awards they can get, and if I was going to try to qualify for regionals the amateur score is actually doable (we will never be qualifying for anything in Open ). Otherwise, not really much of a difference in my experience. There are high scorers in both divisions that’ll be tough to beat.
