Think about the last time you saw a skateboarder. Maybe it was a lone person on the street where you live riding late at night. Maybe it was a group downtown practicing tricks on curbs and benches. Did you happen to notice the skateboards themselves? A new exhibit at the Art Museum of Rochester brings the art of skateboarding up off of the streets. During the installation of Hoarders of Cool, Friends of the ROC City Skate Park President Alan Presutti showed off walls of skateboards. Skateboards that are varied and colorful and in some cases, used.
