Today I counted them all up and it turns out Minnesota is only the 26th state I have visited (for some reason I thought it was higher than that.) Still, sort of a milestone as with Minnesota I can say I have now visited over half of the 50 states.
I have heard of growler places where you prepay for a card and fill up your own beers, but never a bar. I would love that as I am a fan of trying a bunch of different beers (always get a flight at a brewery). I could see this being a legal issue in some states as there is not a bartender actually serving the beer so they can't judge your intoxication level. Although if you are that fargone you probably can figure out the machine anyway.
True but if using a card each time they could put a limit of pours based on time. It would lock out ability to pour more. Not perfect but would help.
