My friend is part of a disaster prep group. After he talked to me about it, I realized I'm really not prepared at all.

I've decided to get supplies that would be helpful in the case of a natural disaster, or in the event of a terrorist attack or something similar. I know I should purchase canned food, bottled water, blankets, flashlights, first aid kit, etc. What are some other things I should include that I might be missing?
