I bought a few bottles of Tank 7 (and the t-shirt) summer of '09. Beers are gone, but still have the T-shirt.
Loved the beer but found out I am seriously allergic to the midwest around Memorial Day weekend.
Boulevard does crank out a lot of basic wheat beer that is taking away market share from BCM, but they are using that volume to fund playing around with a corked "belgian" line and Tank 7 was up among the best they had to offer 18 months ago.
Mrs. BC and I went for the brewery, skipped the tour, and did get to taste some good stuff at the taproom in between the tours groups.
