Not really..... from Manchester, New Hampshire to the stadium it is 77 miles (Yes I am bored and at work!!!!) and Portland, Maine (the first big town along the coast) to the stadium is 135 miles. In American terms, those are short distances to travel - admittedly not for evening games!
I've been to Revs games with 13,000 rattling inside the place but also a couple of times when 30 / 35,000 were there for big games at the end of the season and play offs. Those school buses were coming in from all over New England. The only part of NE that doesn't aligned itself with the Revs (same with the Patriots) is the southern to middle parts of Connecticut that see themselves leaning more towards (or originally from) New York.
