Tim is right about cash, and it is good to be way over prepared. You can go through a lot of goods in a very short period of time during a major emergency.

terrij, we added a new item to our hurricane kit as well. Everyone in our area had signs basically saying "you loot we shoot" etc. One person we saw had two body silhouette's stapled to a piece of plywood labeled his and hers with their scores from the local gun range. They did not have any problems for some reason....

I understand the gun laws of Belize, and know that it may not be nearly as effective to do down there due to the permits requirements etc., but for anyone in the US it was an effective deterrent.
