Visited two different lakes. Unfortunately, it was too cold for swimming (much too cold). But I did rediscover - since my childhood, of course - the fun of hotel pools.
I found it rather interesting that there were floor-length windows on one wall of the pool room. I took a walk down that street, though, and with the daylight outside, you can hardly see anything that's not right beside the window. From inside, though, it makes for a pretty neat contrast, between the humid pool environment, and the people bundled up outside in the cold, blustery weather.
