RE: How would joining the AMA help me?
XSDEVOTEE,
If you're flying "in the sticks", and if the chances of causing damage to something, someone, or yourself are pretty slim, there's no need to join. In the future, if you do move in toward society, you may want to consider joining. There's no rule saying that you have to be taught by an instructor in order to join. It would, however, be a good idea to get checked off by a seasoned pilot, simply for safety reasons.
By the way, I'd like to have some of that 55-60 degree weather myself. Here in northern Louisiana the temps are a steady 85-90 degrees with humidity of around 80-90%. It's not that bad, but the mosquitos are hell!
