A question that seems to come up often reguarding shelters is weather or not those in charge can take things you bring with you to distribute to those without. It sounds bad to think about it but I've ran into people before who seem to expect that you give them your food/water/gear and those are the last people I tend to give things to, I will give someone in need if I can. I had roommates in college who thought everything was public property so I ended up having to hide things just to keep them otherwise I would be out of food the day after I bought it.
