This is Nashville, Indiana. Getting there early in the morning is smart, because then you get free parking and avoid the crowds.
The attraction? Nashville used to be an artist colony. Locals doing their thing and having a good time. Their good sense of taste brought others with taste, and the town flourished.
It still does, but with the money people arrived with more sense for money than taste.
Occasionally there is still a trace of the former times left, like below in the inconspicuously elegant choice of a color pallette.
