Hurricane Relief - What Would You Bring?

andyring asks: "In a few weeks, I will be going with a group from my church down to some of the hardest-hit areas in Louisiana and Mississippi to volunteer in the Hurricane Katrina relief efforts. We will be there six days, and have 10 people going so far. At this point, I don't know much more than we'll be in either Slidell, La. on the northeast shore of Lake Ponchartrain, or Pass Christian, Miss., right on the Gulf Coast near Gulfport/Biloxi. Not knowing what we'll be faced with, and having somewhat limited room for supplies, tools and equipment (probably a U-haul trailer), what would you bring on a journey such as this? Any Slashdot readers between Lincoln, Neb. and the New Orleans area interested in contributing to our effort, such as donations of equipment/supplies/tools/etc?"
