My wife went out a bit earlier to do just that. It hasn't happened yet, but when we flood our water gets contaminated. We had a flood in 09 and they are still trying to get our drinking water under control.
Well...I tried. I was all "Get emergency candles. You know, for emergencies.".
Yankee Candle just made $100 off of me. That's well beyond what my candle budget called for, but at $20 a piece I now have one for each room of the house. My room, 2 kids rooms, living room, kitchen. I was all "You know we could have just carried them with us.", which means I will be enjoying the living room candle from my place on the couch this evening...for safety.
