This is a wonderful photo! My favorite types of source images are ocean/swimming/vacation related. Vacations hold a special place in our collective American memory. They signify; escape, family, and tradition.
In my case, vacations also mean mini-golf, waffle cones, and the feeling of sunshine the skin. Oh, and stopping at every thrift store in sight.
Think I will go outside and get some fresh air!
