There are good photographic opportunities in and around Brattleboro too if there is any interest in getting up there early. In Brat. there are plenty of interesting buildings, people and stuff. A few miles up VT 30 is Stickney brook which ought to be pretty interesting with all the ice that's likely to still be there. (though it might be "challenging" to get down to the water).
I know everyone has google, mapquest and GPS's, but, the easiest route from the Boston area is probably Route 2 to I 91 North to VT exit 1 or 2. Easiest parking is in the transportation center parking garage next to the gallery. You can reach the garage from either Flat Street or Elliot street. Go up or down to the 2nd floor of the garage and there is usually plenty of parking.
From the Garage, the gallery is down the stairs next to the elevator and across the alley. There is also a small parking lot across Flat street from the Gallery.
