Wow! That is almost a 70 degree variation in temperature. I would be surprized if the groups hadn't changed. Maybe this is unrelated, but when I wear thicker clothing my groups shift: I think I am altering my draw because of decreased range of motion. How much extra clothes did you have on? Maybe this changed things a bit?

The question about Maine was because I have a best friend who is a native of Maine and she says "wicked hot" "wicked cold" "wicked cool" etc. and claims it is a Maine-thing.
