Edit of sorts. Just checked the beer finder for Old Nation. Hudson and Eau Claire (so good luck) and Spooner (one might have a shot there).
Beechwood is their distributor which is decent sized. It’s just a matter of does the store order it. I’m sure someplace like Chicones would order in whatever you are looking for if they can.
I’ll agree that sometimes the super popular releases for New Glarus move quick in certain stores in Hudson, others have it longer and if you go a bit further in like Somerset or River Falls you’d find it more easily.
