Replying to Joining Air Force?

I'm really considering joining the Air National Guard. A lot of factors are going into it, and I'm pretty sure once I graduate college in a year I'm going in as an officer. Anyone have any advice/family in the guard? Anyone here in the Air Force? I know a few members are, and I've talked to some. I want to fly for a living, and I feel that going in reserves is great because if i decide I like commercial better, the reserves is part time, and if i like the military, I can make it full time. Advice/Thoughts?
