Quick observation

I was at the pool today doing a quick swim. It was cold outside, so I wasn't exactly warm when I got ready for my swim (yes, my pool is indoors I just hadn't warmed up yet). Needless to say, I was less than enthusiastic about jumping into the water. I finally built up the courage to take the plunge...it wasn't that terrible. I always imagine it being worse than it ends up being.

But here's the kicker. The pool today had 2 distinct temperature zones, comfortable cold and freezing cold. There was a patch of freezing cold water about 10m wide almost right in the center of my lane. It was a shock to the system every lap...I just don't understand how there can be such a temperature difference throughout a pool that small...it's all one body of water. The water gods were playing tricks on me. That is all you get for now. Thanks for listening.
