We think the time has come that the state's exit numbers should be switched from Sequential to Mileage-Based. Most of the states have it all ready for their exits. It would be easier for all of us if the exits were Mileage-Based. By doing it this way, it would be easier for us to determine how far it is to the next interchange, or even, how far it is to the next state. Florida, Georgia, Maine, and Pennsylvania have all switched in the past few years. We feel that it's Massachusetts turn to switch our exit numbers to Mileage-Based.
