Imagine standing on the side of Interstate 4 trying to find an opportunity to cross as semi trucks whir by - only you don’t know exactly what these loud, fast monstrosities are, because in this scenario you are a bear. Maybe there’s a fresh food or water source on the other side of the highway, or you may have been evicted from your home territory by a bigger, stronger bear. Anyway, you’ve left the safety of the trees and have now come to face the dizzying bustle of the roadway.
