I guess I shouldn't be surprised
Earlier today I went to the local lumberyard to pick up some wood for a small project. I went to the service counter and placed my order, and while I waited for the clerk to punch up the ticket I happened to notice a big double-wide cooler right next to the counter.
Stoughton Lumber sells beer. And not just the national brands, either; I checked out the cooler and there were plenty of micro/craft beers right next to the High Life and the PBR. But in same ways it does make sense...when it comes to DIY carpentry around a lot of houses it seems like a few cold ones will eventually put in an appearance, so buying beer at the same time as the wood is pretty efficient! And, of course, there's the whole Wisconsin angle, too.
I'll bet I can't get 2x4s at the liquor store, though.
