Finding gems like this that took place in your city never gets old, especially with Halloween right around the corner. Here’s the back-story:
“It’s an event that sounds part Critical Mass–style ride on the newly elegant Upper West Side, part goofy Halloween costume party for the city’s emerging leisure class.
Thousands of riders decked out in costume cycled up to 108th Street, then turned on to Riverside Drive. From there they went to Claremont Avenue, back to Riverside, and down to 66th Street to finish.”
