Haha funny.
The problem really isnt the mud that is on the ramp, it is the mud that is in the water. As you back the boat/trailer down the ramp, there is a wall of mud about a foot into the water, and it is about 3 feet tall. It would be like backing your trailer into a 3 foot high bank of sand. The mud that is on the actual ramp above the water, really doesnt stop a 4x4 vehicle from using the landing. It is the wall of mud that gets pushed into the water. It is like a big road block for the landing.
