Ultimate Frisbee Monument
Maplewood, New Jersey
A Frisbee-sized-and-shaped plaque on a small rock marks the parking lot where Ultimate Frisbee was first played by its inventors: students from the school newspaper and student council of Columbia High School, which was just across the street. The year was 1968, and the game was then called Frisbee Football, conceived as a counter-culture, non-aggressive non-jock alternative "sport" to the usual high school organized team sports of football and basketball.
The inventors probably would've been shocked to learn that their sport would be honored by a plaque paid for by a bank. It was affixed to the rock in 1989, by which time Ultimate Frisbee was no longer counter-culture.
