People like boats. I like boats, you like boats, we all like boats. Here's a picture of a red one. If you ever find yourself in need of a spot to shoot a sunset over the ocean in Southern Maine you are limited in options. The working docks here at Pine Point in Scarborough are the closest location to me and when I peek out my window around sunset and see the clouds gathering for a possible brilliant sunset I will often hop in the car and make a mad dash down to the waterfront. If the tides are right you can catch a whole beach full of these waiting to take the guys who work on the water out to their boats.
The breakwater in Rockland juts out almost a mile into the ocean protecting the harbor from the worst of winter storms. I'm astounded by the feats of engineering required to produce something as aesthetically simple as a breakwater. I like in this image how you can see the chop on the left and get a feel for how the whole contraption works with the glass smooth water on the harbor side to the right.
