Just another Indian summer? Some years we have them some years we do not. I seem to remember frost on the ground just a couple of days ago. Did you all forget we live in Illinois. weather changes here by the hour not by the season.
Thirty years ago if we'd have had a cold snap they would have blamed the coming "ice age." In my opinion, both are crocks invented by politicians to scare the huddled masses into voting for them, so they can fix the non-existent problem.
