What: Green River Festival
A festival held every summer which combines music (including They Might Be Giants) on two stages, food, crafts, dancing, kids activities, hot air balloons and fireworks.
The festival itself will be held in Greenfield, MA. This is roughly 2 hours from Boston, 3 hours from New York City, 4 hours from Syracuse, and 3 hours from Burlington, VT. There is camping nearby in both state parks and campgrounds (I like this one - we could rent the big field as a group), as well as hotels (for the less adventurous).
The festival takes place on Friday and Saturday, July 18 and 19. I'm planning to stay another day and explore nature!
