Hope for the Warriors yoga

Bring your own mat for an evening of yoga on the Elevated Acre, a grassy rooftop space overlooking the East River. Instructor Denise Olsen—whose husband, Jeff Olsen, was among the firefighters who died responding to the September 11 attacks—leads the hour-long vinyasa flow practice. The open-level event benefits Hope for the Warriors, which assists injured service members and veterans, their families, and the families of those killed in the line of duty after 9/11. Day-of registration starts at 6:30pm.
