Maine's Narrow Gauge Railroad will be up and running again come May 4. Coming to the city this summer? You might want to spend a sunny afternoon along the tracks edging Casco Bay. It's really a short trip, running 1 1/2 miles parallel to Eastern Prom, but well worth your time. The view is terrific! There is a museum too with quite a history of narrow gauge railroading in northern Maine. Choo Choo!
