I'm a huge fan of Bell's (and am currently missing it terribly), but to be fair I feel there are better breweries out there - granted, not many, but they do exist.
I import it from the Midwest to San Francisco. Currently having a Two-Hearted, and I've got a bunch of Oberon in the basement.
Midwest beer nerds trapped in San Francisco should give me a shout.
Yes, and several of them are in Michigan.
Bell's is great, but so are Founders and Short's. (New Holland isn't bad either, but kind of second-tier in comparison.)
