Since you mentioned this I checked the rates at the only fitness club in my town that I know of that has a swimming pool. I used to be a member but remember it was about $50 dollars a month. This is more cost than worth (to me) for the amount of time I ever used it at the time and I recall I didn't like the pool that much for some reason, maybe it wasn't Olympic size or something, I forget now, maybe the humidity or something, I may go check it out again, it has been a very long time since I was in there.
While I was at their website I did see something that gave me quite a shock and almost brought tears to my eyes. It was quite a humbling experience to be honest and the first time it has ever happened to me. I found I can get a membership for about half price....with a senior discount, anyone 55 and over qualifies.

Talk about a cold slap in the face. It really was quite depressing.
