Flying J has spots in front from the trucks but now the bobtail rigs are parking in the RV spots. Last fall going to Denver 3 Flying J 's had Bobtail rigs parked in most RV spots. As I was fueling 4 RV pulled in and left. I went down the road a few miles and went to a Walmart and there where 9 trucks in there also. Went in and asked. Told it was fine for the night so we went shopping there.
