Just E of Bar Harbor. The YC is friendly to transients, and the town is charming. An excellent general store, plus a couple of artsy-fartsy places doing glass work and oil painting - bought stuff at both!
Oh yeah, the fog - it does lift eventually. Recommend waiting it out. We left Bucks Hbr one morning in the fog heading W with the radar going, then realized there were nuts out there barreling through the fog at 20+ knots. We did a U turn and headed back in to Lem's Harbor, relaxed, and waited things out.
