At the Gothenburg, Nebraska exit on I-80 you can go north or south. On the north side is a large truck stop, two gas stations, and a diner. On the south side is a two-pump gas station that doubles as the camp store for a KOA. I stepped into that store and was absolutely gobsmacked!
It’s got minimal convenience store items. It also has the widest selection of British market goods I’ve ever seen outside the UK!!
