Pisces Link?

I have started swimming at the YMCA. I really, truly enjoy it. I swam as kid and on and off through the years. Before kids, I went to the gym regularly, but swimming was always tough. For some reason, it is coming together for me now. I enjoy the cool water and the solitude - just me and the water. I swim about a mile - sometimes more, sometimes less. I am even getting better at my strokes. I have always loved the breaststroke, but freestyle tires me out. Freestyle is even getting easier. I notice some small changes, but the bigger draw is that I really like it. I am toying with the idea of doing a triathlon (sprint version). The big drawback isn't the running with which I have a love/hate relationship. The part that scares the beejesus out of me is swimming in TEMPE TOWN LAKE - BLECH.
