Riverside Park’s Howl-o-Ween Costume Party will be going down tomorrow, Saturday from 12 to 3pm. It was originally scheduled for Sunday, but there’s rain in Sunday’s forecast, so it has been rescheduled.
To be clear, this is a Halloween costume party for dogs.

c/o Riverside Park Conservancy
The event is being organized by the volunteer-led Riverside Park D.O.G. (“Dog Owner’s Group”). All proceeds improve spaces & amenities for dogs and their people throughout Riverside Park.
