I think I've figure this out. I'm going to take three pallets and cover them with some wire fence I have that is 2"x4". Then I'll tie them in a triangle. I will tie in 4 Trees on the pallets by scalping one side of each and laying to two sides of the triangle. I may cut two of the pallets down about 4" so the angle the trees will be on is steeper. Then I'll cut some fence to cover the ends. I have a pile of 3" limestone and I'll put 8-5 gallon buckets inside the triangle before I close it up. I'll drag that onto the ice. 8-5 gallon buckets of stone should weigh in at almost 600 pounds. I gotta think that will sink that hog.

I figure that will provide cover for the small fish and overhanging cover for the bigger ones.
