Jeff,
If you want to join the CAP, go for it man. I used to work at an FBO (fixed base operator) at a fairly large (Class C airspace) airport. The CAP came in most weekends when they would go and fly their C172. One of their commanders was an ex C-9 driver. They were nice folks, some took themselves too seriously. Same thing happens in the fire and police service with the Explorer program. Just look at it as an opportunity to learn more about aviation, and get some free stick time. I really enjoyed teaching the cadets about the airplanes that my company owned. Best of luck.
