will stay in Maine, but I could be persuaded to go to one of those other states if there was something great to see there. I basically just included those in my post so I didn't limit my options while I'm making plans. But I agree that I wouldn't want to be driving all over those three states in a span of just a few days.
As far as my interests go, while I do like the mountains, I also really enjoy the ocean. So I think I'll stay along the coast in Maine, at least mostly.
