Those sharp eyed observers out there may have noticed a patch of blue in the upper left hand corner of the picture. Yes, it is a tarp. We have significant holes cut in the roof to get accurate measurements. On Sunday right after church it started to rain. I went out in the rain and put up a couple of tarps to cover the cut outs. It also rained again on Thursday morning.
