For those that want an alternative to MREs due to limited storage space or other reasons, you may want to consider some of the stuff from Backpackers Pantry

Some of it was a little boring and pretty pricey (there are usually cheaper and sometimes as tastey alternatives, especially soup/oatmeal porridge at most grocery stores) but their Beef Sroganoff entre is absolutely delicious. Although, if I recall, my daughter and I consumed a four person serving at one sitting. Then again we were burning off a lot of calories.

Also consider packing something for siphoning gas. If one has more that one vehicle, the gas in a spare vehicle might come in handy.
