Excellent, Greg and hope that it is not even considering placing a nest on top of that! A pair built a flimsy nest on top of a pontoon boat and cover which was on our neighbor's boat lift and part of it was even under the cover, and believe that they were a young pair. When my neighbor told me about it I thought that perhaps they were just using the boat as a perch but when I put the glasses on it, there they were on the nest!
