I like swimming and its really good exercise, especially when its a bit chilly. My first swimming lessons were in the spring, but it was in Ohio and 40 degrees outside in an outdoor pool. At least the water was warmer. You can bet we didn't waste any time standing around.
When my younger became a competitive swimmer it was even better, because his older teammates were fun and good looking. I became a timer, and later a diving judge, partially because the scenery was so good.
