I had this Imperial Oktoberfest on tap this week and thought it was really good. I checked out Meadows and Beer Baron but no go. Thanks!
I found a bottle at Main Party Store in Ann Arbor a few weeks ago, but it was from 2011, so my guess is that distribution is sparse to this area, or they get nabbed quickly. If it's not too long of a drive it may be worth checking out, although I'm not positive they still have any.
