From blog.askasheville.com:
Get ready for the Asheville Tweetup and Facebook Flash Mob of the Year in downtown Asheville North Carolina. On December 27th, just 2 short days after Christmas, a bunch of us are getting together to go downtown and have some fun.
Who will be there? Lots of folks from Twitter and Facebook; and anyone is welcome. You can come in pairs, come as a group, or come by yourself. If you come alone, just ask for AskAsheville and hang out with us
What time will it start? We are meeting at 7pm near Pack Square at the Vance Monument, and heading for some fun flash mobbing at 7:15 from there.
