cleared off cold frame

My son went out this evening and cleared the heavy snow and ice layer off of my cold frame (for a small fee...). It was a good foot of heavy ice and slush and I was afraid it would crush the panels. We have not had a winter like this that I can remember and the panels were not designed to hold hundreds of pounds of weight. The panels still look fine. Now they are ready to get covered with another snow layer again - I hear another storm is coming on Saturday.
