Have you thought about starting a 'class' at one of the local gyms? I know that at the Nampa Rec Center, there are a bunch of classes that meet periodically. If you could get in touch with one of the managers there, I'm almost positive that they would love to offer another class. Also, I am willing to bet that the costs would be fairly low - just a weekly renting of certain parts of the gym (ex. gymnastics area for general practice, weight room for strength training, rock wall for the obvious, or the pool for recovery and technique practice) and passes for the members. The passes would probably be around 30 bucks for a month, maybe less. I know that the rock wall passes for the upcoming event (Jan 26 - March 7) are $27 for people without memberships, so it shouldn't be very expensive. If you need more random ideas, just ask.
