Anyone have any idea what the best (non-tent) things I could bring to the folks at Occupy Edinburgh this afternoon to help with the rain are?

I’m about to go up, but I feel like I ought to bring them something since they need donations. I don’t have a tent, but I’m considering just bringing a large piece of fleece to act as a blanket(s), since fleece tends to stay warm when wet.

I’ve no idea though, since the things they need most are the things I don’t have.
