Oh, you could certainly ride in coach to Wolf Point and start the AGR trip from there, and then it almost certainly would be a 2-zone trip. My guess of the spread for the trip starting in Columbus is that there is a 55% chance the agent will say it's a 3-zone trip, a 40% chance that it's a 2-zone trip, and a 5% chance that the agent either will claim that it can't be booked, or that it's a one-zone trip.
