I do know that school masters offer a lot and are great tutors for developing your riding education further.
I think it's the first step you can do and after found a job in a good place 😉
My stable has an IEA team for the teens which is an interscholastic Equestria association team which means my team competes all over the US (if we get that high up) mostly we stay in our region. My other barn had a polo club. You just have to ask around ask people at your barn. Or you can make one yourself :)
