I drive down from Southern, NH in my Blazer. In all honesty, it is faster and cheaper for me to drive. The bus out of Londonderry has a very limited schedule. So, my other option is to drive to Woburn, take the train and then walk clear across the city (lots of fun in February). It adds about an hour to my commute each way and the gas from Woburn to Boston isn't making a huge difference.
My DH built the new N. Attleboro police station (he was the electrical contractor). He drove back and forth every day....on Fridays, it took him about 3 hours to get home. Not fun.
That's so funny that you were in the building today....I often wonder if I'm sitting in traffic next to a fellow DISer if they have anything Disney on their car.
