This is the stretch of Fifth Avenue where the Red-tailed Hawks nest, third building from the left. Like me, they go back and forth from the City to the Park, so the division, though sharply drawn, is not impermeable, and the creatures of one are the creatures of the other.

The seasons are a different sort of boundary; no passing between at will; only an enforced circuit. So we must appreciate each in its time. Now we’ve crossed another threshold, vacating Spring.
Summer is here.
I’m gone.
