Tiny islands are wonderful places - ones with few to no cars are the best. Peaks Island is a 20 minute ferry ride from Portland and about 1 mile wide and 2 miles long with a population of 1,000. There are a few cars but most people get by with bikes (though golf carts are pretty popular with the older folks).

A custom seat cover outside the corner store. A lovely match for Gerhard Richter's "Betty" - a painting he made of his daughter in 1988 and one of my favorites...
