An interesting tip is circulating online suggesting that you place a quarter on top of a frozen cup of water in your freezer before you evacuate for a hurricane. Why? It is a low tech but ingenious method of knowing if your power was off while you were away. Of course, this is important to know since you don’t want to assume your frozen and refrigerated food is still good just because it is cold at the time you return. If the quarter is still on top of the cup, your power was not off long enough for the ice to melt. Brilliant!
