Spudbob gets by sans power

Spudbob: Day 3 and Casa de Spud (near CdA public golf course) is still without power. Gas water heater and fireplace in basement so we are getting by. We have candles and flashlights however I am getting pretty tired of stumbling around in the near darkness. This morning the house was as cold as a crypt. I left the house for work early this morning (mostly to warm up) and on the way noticed that in the areas that do have power many people had left outdoor lights on all night. I have never even considered doing that and it got me wondering how many of the merry hucksters do.

Question: Do you leave outdoor lights on all night?
