I read a great tip yesterday. If you're evacuating, when you come back, you will want to know if the food in your freezer thawed out and re-froze, or if it stayed frozen. So, take a plastic cup, and put a couple of inches of water in it, and freeze it. Then put a quarter on top. Put it in your freezer. If you come home, and the quarter is frozen under the ice, then you know that the electricity was off long enough for everything in the freezer to get warm enough to thaw out. Then you know to throw out your frozen meat or anything else that may have gone bad.
