Before leaving the west, we must stop at my favorite cow town dive bar. Billings is the heart of Montana’s cattle country. This former train town is home to one of the country’s largest bull auctions and home to one of my favorite dive bars. The Rainbow is where local come to mingle and sip on PBR. The menu also includes pickled eggs and pigs feet. If the ambiance is not enough be sure to test your skill on the shuffleboard table.
