How widely available is this now? Taking a trip to Michigan and would like to try it. I'm going to Traverse City but will be stopping in Grand Rapids.
It's very widely available, but it does still sell out at some stores. Your best bet is large grocery stores (Meijer) with great beer selections. Grocery stores often have the freshest available because they move so much at the best prices.
I agree with @Lazhal. At most, you'd have to stop at two stores to find some. The cans are dated so check that out to make sure you're not in a slow-moving store.
