You can look for one that allows you to mail in a project instead of doing something onsite. I know many here are doing blankets for Project Linus. We did a book drive for the USO. We were told to collect 6-8 books per person, from a list they provided, but we ended up with (I think) 72 books for the 5 of us. The books could be new or "gently" used. I sent them to a USO base in Qatar. Nothing was showing for my area (central MS) but I read on another site to type in Normal, IL and mail-in projects would be available. There was also an opportunity to do Haiti care kits.
We mailed the books, and within the week had our vouchers ready to print. And we had a lot of fun doing it.
You can get more ideas on the GAD board, under the theme parks board on this site.
