Which type of body of water do you swim in?

Septic Tank.

It's not so much that I can't swim, it's that I don't swim.

Municipal water supplies.

I like any natural body of water, lakes, creeks, rivers, oceans. I don't care for pools that much. I don't like the feeling that I am swimming in chemicals and I am the type to just jump in for fun on impulse and treated pool water is hard on clothes.

There's so many choices. Lets see there's a big winding river south of where I live, and some pretty well known lakes north of me, and to the east there's the Atlantic and to the west I could swim in the pacific. My neighbor has a pool...hmm and my grandmas back yard currently resembles a swamp, which as you can imagine has her overjoyed. I also have this thing I call a bathtub but when I'm drunk it's a boat and I'm trapped in the ocean with a tiger, so I usually avoid it while drinking. I also avoid baking but for a completely non related reason.
