It's always hilarious to have people from hot climates, like Florida, come up north to see what real weather is like. I was in Michigan camping, and these 2 girls were from Florida. It would get to about 55*F at night, which I like the best, yet they were soo deathly cold. My uncle is visiting in December....he's from North Carolina....
If anyone is going to come up to Massachusetts, come during October, during the fall foliage.
