Nature: Tired Grove: Tread Lightly

As Racer Dave goes to pick a new set of tires from his favorite grove of tire trees, he spots Biker Steve and Auto Annie. Steve had fallen and Annie was trying to help him up. Dave couldn't help but laugh. Off in the distance is Coasting Bob with his loyal pup Sparks, searching for a pair of new tires for his bicycle.

In a world of drivers, tires grow on trees.
