So I see from your signature that you're in Nebraska. I suspect that you might have a hard time finding a true eventing instructor. You can always check this website to see if there are any certified instructors within driving range. http://useventing.com/education/icp/...structors-area
I know that there is one event, Feather Creek, down in OK. (I'm in Kansas, so we've gone down a few times) You could contact the owners about training, I think they offer lessons? They might also know if there are any trainers around? http://www.feathercreekfarm.com/
You could also ask around to see if you could find any straight jumping instructors. I don't know if you jump or not, but if you don't you definitely don't want to start out on XC.
I feel your pain, trust me, often times we've had to trailer 1.5+ hours just to get good jumping instruction.
