Did you ever get this ID'd? I've been recording 50704 it from the Miami site over here in Joplin.
Lots of brief, chit-chat type comments,(order of fries, tomatoes and oranges - altho the more I listen I think this is *code* for types of currency), mainly women. "Lane 2 hold your traffic", "Class 2" (license?). "this is Big Cabin" "he got a green light" "she would pay their toll" like Turnpike folk. "didn't pay at mainline, charge from Stroud", "a toll tag violated"
WITH no objection I'll call this "Turnpike toll booths" and send it to the database.
