I saw an MCI today (I assume one of the new ones) deadheading south on IL53 through Romeoville at about 6:30 PM. I saw the right side of it, Interestingly it was wrapped except for the lettering. It had the white stripe toward the rear, but it didn't say "Authorized to use the shoulder" on the stripe. It did not have the Pace express logo either.
6510-12 have been running unwrapped, so it is not "impossible" for them to be on those routes. Has anyone seen one of the unwrapped buses actually driving on the shoulder?
