I don't think the season (month) has anything to do with when or when not to go on the ice. If it has been cold enough to make 5" of ice, I would consider that safe. I watched the newscast and was embarrassed by it. I'm sure the parents checked as they went out, as did the fishermen, spud, walk, spud, walk. Pretty simple.
I agree with you Brian and Terry, and I would follow you out there too!
