Truck Driver 1: "Hey Red-Rider, what's your 10-20?"
Truck Driver 2: "I'm 'bout 3 miles from the rest area off of I-95 just south of Springfield"
Truck Driver 1: "Ya'all should pull in there and take a break there's an Ocho Cinco hanging out there right now that made it worth the stop."
Truck Driver 2: "10-4 on that...I think I'll be dropping off my load before I get to my final destination."
