There is nothing like a walk along the Charles River at sunset in the Fall. I love watching the crew boats practicing for the upcoming Head of the Charles, with their totally in sync movements and their bodies nearly submerged in the opaque Charles.
Patterns of migratory birds and the quickly setting sun grace the sky. On the ground is the zinging of bicycles as they fly by and the steady thump of the ever present runners.
The cool breeze coming off the river reminds you that it is now October and our indian summer is coming to an end. Soon the trees lining the Esplanade will turn a brilliant shades of red or yellow or orange and coats and hats will make their seasonal appearance, too. I love Fall in Boston.
