When I was at the Davis Campus for yoga the other day, I saw a sign on the billboards for a clothing exchange. It's October 23rd (2 saturdays from now) from 10 AM-1 PM. It doesn't say anything about bringing a set amount of clothes to be admitted or anything like that, so I say just go. Bring stuff if you have it, that's the nice thing to do. They'll also serve refreshments. I wasn't able to find any more information on the website, but if I do, I'll post updates. I'm planning on being there!
