The fox was probably on the way to visit the raccoons who are taking over your neighborhood, the wolf-coyote hybrids who are prowling your park, and the deer who are munching on your parsley. Despite the fact that the bus was empty, the fox only took up one seat. If only all encroaching wildlife (including humans) were so polite.
Have no fear: The fantastic little guy snuck onto the parked bus for a snoozer and left on his own accord (feeling refreshed, we hope, and ready to seize the day — or somebody’s tasty backyard chickens!).
