I'm getting my first eventing lesson Thursday! I'm a western rider, with a few English lessons under my belt, but I am moving to a mostly English barn in a month and a half, so my dads ex girlfriend, who is a top eventer, offered to help me out and give me lessons! For free! What should I expect from my first lesson? And if there are any other former western riders who switched to English/eventing, what was the biggest adjustment you had to make, aside from the different saddles?
