Share 'GM-Sponsored Tweetup in August'

Hi everyone, I'd like to have a GM-sponsored Tweetup at the GM Heritage Center in Warren on Friday, August 15. Since that night is the eve of the Woodward Dream Cruise, GM is throwing a party complete with drive-in movies and tons (literally!) of cool cars. It runs from 7 - 9 p.m. What do you think? Here's a link to the Heritage Center's Web site. It's a really cool place. http://www.gm.com/co…
