I guess I'm more curious about the flying. I can put up with some stuff if I get to fly a well equipped plane for cheaper.
You can definitely fly for free in CAP but you have to really work to get into flight status. Because CAP is the Air Force Auxiliary, there are rules, regulation and qualifications to go through just like in the military. There are several smaller ones, but the biggest immediate one is that you must fly a checkride with a CAP instructor for your highest rating to PTS standards and then repeat that annually.
Keep in mind that the flying in CAP is not really pleasure flying. You can pay for your own flight (at a really good rate) and fly for proficiency but it's not a hamburger run. You can only have other CAP personnel in the airplane and you have to fly by their rules regarding checking in/out, formal W&B, flight risk analysis, etc. Eventually you'll be expected to qualify as a "working pilot", for example as a Mission Pilot capable of flying search and rescue and photography missions. Or perhaps to fly cadet orientation flights, taking CAP cadets up to teach them about airplanes, kind of a Young Eagles. All this while also participating in a squadron role to help keep the admin running on the ground. There is work involved.
For doing all that, you can get the Air Force to pay for 100% of some of your flying, in a G-1000 182 or maybe a 206 or 172. Depending on how much you do, that could be a very significant number of hours doing some really interesting stuff. CAP was heavily involved with disaster recovery efforts for the oil spill in the Gulf as well as survey work of the damage from Hurricane Sandy, flooding and tornadoes. I know people who have played "red force" for USCG or USAF drug interdiction training.
In the end, there are fun things to do and you can also get free flying along the way. But it's not for everyone, so give it a try and see if you like the people in that immediate squadron, at least enough to pay the $76 annual dues and join for a year. A blue polo shirt with the CAP logo + grey slacks is the only required uniform. The first year costs are about an hour or two of flight time, that isn't much to lose.
Like I said above - there are people who like it and those who think the whole organization is a waste of time. I say decide for yourself.
