Cracker Barrel and Pilot/Flying J questions

Oh, am a retired over the road driver, I have spent many overnights in truckstops. In my honest opinion, truckstops and rest areas are the last places I would want to park overnight at. I have seen every form of illegal activity taking place in theses places. Was in a truck stop where you did not dare walk out the door to go to your truck because some "flipped out" trucker was using the parking lot as a demolition derby track. Have seen drug deals going down, and lot lizards (hookers) knocking on doors of trucks while their pimps were keeping watch. And always somebody with a scam going on. And if you ever end up parked between two refrigerated trailers with their reefer units running, you will not sleep! Feel much safer in a Walmart parking lot!!!
