Emergency Kits - What's in Yours?

Well after more than 48 hours of cooking over a propane grill and boiling water over sterno gels we have power back in our little section of Western MA! It has been a rough couple of days. Needless to say DH and I will be putting together a survival kit for the next time something like this happens (hopefully not for a long time!)

Do you have a survival kit in case of emergency? If so, what do you have in it?
