Sailing:

So I am officially a member of JPYC, so I can take out one of their 13' sailboats whenever I want. I can fit probably two other people, and will need a bit of help to get the boat out, but it shouldn't be much work. So if you want to come with some time, drop me an email.

It really is lots of fun. There's something about being in such a small boat on the lake, that, well, you feel as close to the water as you can, and you can get decent speed even on a not very windy day.
