I always thought drinking & driving was illegal anyplace but I did visit a bar once that had a drive-up window.. The window looked right in behind the bar. If the bartender saw a vehicle pull up he could see what you needed and still remain behind the bar. We pulled up and got a couple beers to go. This was in Wyoming circa 2006..... I forgot exactly where it was (it was out in the boonies) but Casper was the nearest town of any size. I'm guessing it was only for "to go" orders that you were gonna take someplace else to consume, right? (grin).
