Our friends from Ohio who will be on the 9 day portion of the b2b mentioned Beavertails. I’ve never heard of them. The last time we were in Portland, we found a donut shop. Have no clue what the name of it was. Bar Harbor might be a good place for your hubby to find a lobster roll. Just go early because last time a ship was in port, some restaurants ran out of them. We are geocachers, but have already found geocaches in all these places!!
