Yes, there is a mild crispness in the air, but that occurred in lat August as well.
The fruits in the store have changes, crisp apples and pears.
There was a tree i passes the other day and at first glance, i thought there were oranges,
but no those were orange leaves.
My favorite small tree, the Autumn scarlet, on the north side of the house is beginning to turn also.
The most tell sign, tho, are the frantic dances of the honey bees, drawing the last sweetness from everywhere, even my sweet coffee!
