I thought about suggesting one of those too. Having just come back from a weekend fishing trip with mine, the only problem I see is a way to inflate the tube. Mine uses a truck inner tube which has a valve like you would find on a gas station air hose. I think some of the newer ones use a valve that you can inflate by mouth. I had a thorn punch a hole in mine while slogging to a back country lake. Trust me, it's a .... ahem ...."sinking" feeling to hear air hissing out of your float tube while you are out in a lake in which you can no longer see the bottom. Fortunately, I had a patch kit and a bicycle pump in the truck so the trip wasn't completely shot.

Having said that, wolfpack, I personally think a float tube might be a good option for you. You will still get wet however so you would still need to take the appropriate precautions (bagging your supplies, dry clothes to change into, etc .....). Also, if you decide to go that route, think about how you would inflate the tube. Depending on the kind of tube you get, they are not terribly expensive. I think it's a great idea.
