Lake 32 was reportedly 14.6 degrees. Only if they stuck the thermometer up a duck's arse it was. Unlike last Thursday's swim (different lake) I got colder as the swim progressed. That was apparently 12 degrees and was comparitively tropical. Still, it was good fun, even if I was the slowest there.
BTW, 2 people were swimming without wetsuits. Only one of them had natural insulation.
