What do You Need for Long Power Outages?

Have you ever read those emergency supply lists that the utility company sends out each fall with one of your bills and think that it won't apply to you? We have, and it turns out that we need to make one of our own lists for supplies that apply to us. For example,

1. Lamp oil which always seems to clog the shelves at Micheals was sold out yesterday, we had enough for one more night. 
2. Plastic cat litter containers- I know not green to have those big containers, but they came in handy for water from our neighbor for toilets.
3. Paper Plates - we only ate two meals in, but still had to deal with the dishes. Thankfully we had melting snow on the roof, so my husband rinsed them that way.
4. Drinking water- was down to three bottles. We had been trying to keep that purchase down to a minimum.

50 hours without power was not the end of the world, we had no structural damage, everyone was okay and the library was a fun place to hang out at for 3 hours while my son did homework. Luckily, it was at the end of the week, so there wasn't a lot of food in the refrigerator and I did not open the freezer, food lost is minimal. We had fun playing UNO, Racko, and cribbage. My feelings aren't too hurt that they wouldn't play Scrabble.

What supplies would you need that aren't on the list from the Utility company if you were without power for long than a day?
And for showers- Luckily, my husband's company has showers in their restrooms, very nice ones and my neighbor had a generator which meant my teenager got his shower in yesterday. No shower in the morgue needed!
