Official change of the season

There are various ways to mark the change of seasons.  Some rely on equinoxes and solstices.  I, however, use two indicators, both of which were evident today.  The first is the maximum colors of trees before the leaves begin shedding in earnest.

I saw these wonderful colors on a casual stroll around the neighborhood: maroon, red, orange, and rainbow.

The second indicator was the sight of the city workers beginning to drape Christmas lights on trees in the boulevard.
