Dave finds and extracts the C-channel, which we left last October on the ground next to the radiometer truck. What were we thinking?
The Jeep, parked at cabin #1.
Haoyu and the A-frame, as viewed from the radiometer truck porch. The rotator is on the ground, awaiting mounting on the A-frame, and the C-channel is resting on the A-frame to take some sun and melt the frozen litter off.
