Did my pretrip, everything is fine. Anytime I parked today it was either a pull in or a dirt lot rest area [i15 sb in nevada] I go through Cali check station, I wasn't ticketed. I park at Peggy sues to enjoy a great breakfast before making my delivery and then taking home time, and i find this on post trip. I feel like I would have felt it, seen it. I'm just at a loss and I don't know how or when. Any help? Thoughts?
