On Monday afternoons, I often find myself in the Portland area with some free time. If it's a warm day, I like to grab a sandwich and head for Spring Point Light. There's a nice shore walk to get there, or you can park nearby the campus at SMCC. The granite block breakwater is about 300 yards long, and provides many spots to sit, dangle your legs, and watch the passing boat traffic. On any given day you can see the ferries on their way to the islands of Casco Bay, and some times The Cat, the giant double-hulled ferry which runs between Portland Harbor and New Brunswick, Nova Scotia, as well as innumerable fishing and recreational boats.
As the weather turns, the jetty will become treacherous! Enjoy the Big Light walk before the snow falls. If it's Monday afternoon, I may see you there.
