I want to swim, where can I?

Hi, I'm new to the forum and this is my first post. I want to start swimming (just for fitness) distance, and just see how far I go and keep working at it. I'm an 18 year old male in northeast PA. I have a pool but its too small to keep swimming back and forth for distance. Where do you guys swim at? Should I get a membership at my local CYC or something? I want a large pool (indoor or out) with lanes so I can swim straight and not bother anyone. I've been very reclusive for a while because I've been depressed from a few personal problems I have/have endured. I know how exercise is used to treat mild depression and I'm kind of a physical kind of person so I thought I'd give it a shot. My only problem is I don't know where I can swim at... Where do you guys do it? Is there a club or some national fitness center that has a large pool with lanes for swimming. I don't want a pool with like 100 people in it doing cannon balls.... Thanks and I look forward to becoming a regular here and in the pool.
