I love my stable, but we don't have any instructors based there, and can bring in anyone we want from outside.
Mostly I trail ride for pleasure, but have been thinking about maybe doing a once/month lesson just to make sure I don't let any bad habits slip in.
I occasionally see an ad for one, but I know there must be several more around, and I'm not really sure where to find them. Most of my past riding experience took place 1700 miles away, before I moved here. So I'm not all that plugged into the local community yet.
