Park In September
It's warm, bordering on almost too warm. But, you know fall is encroaching, and that makes the sun all the more welcome on your skin. You can move to the shade of any number of large trees if you choose.
The view is expansive, mountains in the distance beckon to be explored, when you are ready. The small lake across from you reflects the blue sky. There are other people around, but they are only characters in a book.
You can passively watch them, make up stories in your head, and let them go. You are just an observer here, soaking up the late summer sun.
The dappling of the light under the trees is almost hypnotic, and would be easy to drift into a light doze on your blanket. You don't have to be anywhere to be, and the dog is snoring peacefully next to you.
