Whatever you do, DON'T hold it at a stadium!!!
(Not that I think you would.
)
In addition to whatever you plan, you could start up one of those donations for tickets at the club and at Merriweather events like you've been doing in December. You may also want to include items such as tooth brushes and tooth paste, toilet paper, shampoo and other toiletries, phone cards, Metro passes, gift certificates to stores such as Target or other places that people can buy what they need, etc... All non-perishable items, of course.
In fact, maybe you can get some appropriate area merchant to work with you on this and have them provide gift certificates to those who come to the area for the exchange of using their name on the bill. Besides, they can write it off of their taxes while looking good to the community and adding a little help in the bucket. A little lagniape, as they say.
