Michigan has something like 70 breweries, according to the Michigan Brew Tour site. Who knew? Not only does that site have a linked list of breweries, but I like this idea:

Not only did we want to visit every Microbrew in Michigan, we also "had to have" a souvenir growler. Nothing better than bringing some microbrew home.

Picking up a growler from each visit. I wish I’d thought of that. They’re up to 63 so far.
