You have to move around to find a spot thats less weedy. Thats what I do. The fleas are really bad this year but they are heavy when they first start, then it will level off.
The grass is really a pain, I have to watch from the helm and try to steer around them. Its bad around the 4th as there are lots of boats whippin up the water and sending the grass out in the lake.
