We came out of a restaurant and saw a raven that had gotten into a box full of fishing gear on an unattended boat trailer. The raven was fascinated with a foam float with a hole in the middle. It took the float up on top of an abandoned shack and began playing a game where it would toss the float off the top of the roof, and chase it as it bounced down the roof. Again and again the bird played the game, until the float bounced into a deep hole. By that time another raven had come to investigate all the commotion, and the two of them set about exploring the rest of the contents in the box.
