I had the same problem and ended up buying a sled. I know it isn't close to home for you but you'll want to make a trip or two to the columbia and a sled is the better way to do it. There is just so many more places to fish a sled. A drift boat is great for small waters and the OP, but you'll miss out on a lot of other fishing that I guarrantee you'll enjoy.
