going to "the lake"

I'm going to the lake tomorrow.  We're having our annual staff outing.  I enjoy going to the lake and I will sit and visit with my co-workers, enjoy a lavish picnic carry-in lunch, perhaps ride in a boat, enjoy the cool breezes and view across the lake, but I will not swim.  I am not a lake swimmer.  Weeds and yucky muck cover the bottom of many lakes, and strange beasties swim around in there.  When I was a teen I was swimming in a lake with friends when something bumped me on the shoulder.  It turned out to be a dead turtle floating by.  That was the beginning of my aversion to lake swimming.  Give me a nice clear pool every time!
