I used to live in New Brunswick near St. John, and we'd venture back in to the US and Maine. Many trips for Lobster, and to Bar Harbor (Bah Hahbah) . The border city is pretty nice too. A few of our local TV stations were from Bangor and the coastal views are amazing. I always liked Maine.
Driving across the state on our trips further south for some skiing in VT, there was a road known locally as the "Roller Coaster" and it required large doses of dramamine.
