Autumn

Fall in Florida...

...when the air conditioning actually shuts off for part of the evening.

...when many migratory, protected, species fly south for the winter.  Species which can be identified by the bright plumage on the back of their cars... New Yorker, Pennsylvanian, Michigander...

...when a school bus will stop traffic across three lanes to wait until someone inside the daycare wakes up and notices it.

...when traffic triples from the protected migratory species winter hunting pattern asserts itself into the local circle of life and the "early bird" is nearly wiped out.
