I was replacing the tarp on my 4 X 8 semi portable- semi permanent tarp shanty when a light bulb went off. If I made the 2 x 4 skis, floor, and hinged frame for a second tarp shack (cutting only half an arch on each plywood end and butting them together) and placed the two shacks side by side I could run a larger tarp over the entire rig and have an 8 x 8 shack and tow it onto the ice one half at a time. Four 2 x 4 to support the tarp roof and I will have a much larger modified tarp shack with eight jigging holes. 8)
