Re: Floats- rafts, noodles, tubes?
I'm a fan of those kiddie row boats you find for $5 at the store. You can lay down, paddle around with your arms and be wet enough to stay cool but dry off if you get chilly. As a side benefit, they make awesome fishing aids, as you can paddle into the really branch-laden areas and catch those uncatchable fish on them. Of course, getting the fish off the hook while laying down on a cheezy inflatable boat is risky, but worth it when you hook a fish big enough to pull you around (free propulsion).
