I miss that place. Used to go up to Portsmouth frequently for business trips, but I never did any photography up there.
Not much to do up there after dark, though. I remember one time my co-workers and I decided to go exploring on a Sunday night and all of Maine was closed - until we got to Freeport. Stopped in the LL Bean store, had some Ben & Jerry's, and went back home to Portsmouth.
Such an adventurous life.
