The local LR tweetup group is working with other twitter groups around the world to put on a series of local "twestivals" supporting non-profits. 

 The Little Rock Twestival will be supporting Reach Out and Read Arkansas, which is a non profit providing books to children and supporting childeren's literacy.

It’s ten bucks and a book.  Visit http://littlerock.twestival.com to get more details. Of course if you don't want to help small children learn to read I understand (actually I don't, you are cold and heartless)
