+1 on looking into the local masters program. I am fortunate enough to work at a pool where the masters swim, so I can work out with them for free. I have learned so much from them, they are all very friendly and willing to give you pointers and even some drills to work on. Especially since most of the masters swimmers have been swimming all their life, sometimes pro, and include many triathletes, its just a really nice community to get involved in.
