Pulling is highly effective, but if you are like me, that gets old in a hurry. I removed 20 canoe loads last summer, and it didn't even look like I did anything. \:\(

I am looking at saving for one of those lake mowers that mount to a boat and run off of a deep cycle battery. I think they are called Jensen lake mowers. They are expensive, but my time is worth more. Besides, it gives me an excuse to get another really cool toy. \:D
