Roadkill and the return of the geese

It's crazy the amount of roadkill I've seen while driving around town.

Natural selection at work.

It's like animals forgot how to properly cross the street while they were hiding out for the winter time.

Also, the dreaded geese are back. They're lounging around the parking lot. They're chilling on the lawn. And of course, they're milling about the sidewalk.

Why is it that geese are able to fly, but they always walk when crossing the street?
