Back in ‘80 a couple of friends and I went to Glacier Park in MT and crossed over the border for an afternoon to drink in the hotel at Waterton Lake.
It was a kick to see Bud/Bush/Miller/Mic, etc. listed as imported and Moosehead and Molson listed as domestic.
Heh, I have had that same experience, which is both disorienting and humorous at the same time!
