Ommegang is releasing "Inauguration Ale 2009", aka Obamagang, and their press release says it'll be somewhere in Chicago.
"The TTB won't let us call the beer Obamagang on the keg label. So it will be known legally as Inauguration Ale 2009, but the tap handles will be more...um...direct. The style lies between a porter and stout, with a bit of Kriek and a touch of chocolate blended in. It will be on draft only, beginning with the inauguration - in limited areas including DC, NYC, Syracuse, Philly, Chicago and Boston. "
