I Think I Saw Secret Service Arriving In New Bedford

I saw something kind of cool at New Bedford Regional Airport on Friday evening.  Some SUV's were parked on the tarmac inside the fence while a large turbo prop-jet was landing.   When the plane taxied to the ramp, the SUV's sped out to meet the plane.  I then saw some men in black suits and sunglasses walk off the plane and climb into the SUV's.   They sped off and shortly after and the plane re-fueled and took-off into the evening sky.

I then remembered that Vice President Joe Biden was expected at a rally at UMass Dartmouth on the following day.  So perhaps this was part of the Secret Service detail that travels in advance of his visit.   Just guessing, but that's what my little mind came up with.
