Meanwhile inside was almost tropical:Next year I'll feel a whole lot more secure with the poly carb roof panels. Using a 20 ft rake on 4 mil poly is a bit scary. Need to replace about 4 of those rafters. I find that about 10 - 20% of the pt 2x4s will twist and carry on like that one in this pic. Good to let them do their thing for awhile before permanent cover is installed. I have not secured them in the hangers yet so replacement is still easy.
