Mainers like to boast that they live in the nation’s most heavily forested state, but residents paid a heavy price for that distinction when a deadly nor’easter whipped the coast with winds gusting to 81 mph.

By Friday, utility crews from as far away as Nova Scotia and Pennsylvania were converging on the last pockets of homes still in the dark.
