Although you asked for NYC area AND Spring/Summer..... I'm going to give you information on neither of those things!
Echoing the above: We'd love to have you all this fall at Ruckus. No 2016 information yet except date (October 29th, 2016) and venue (The
haunted Main Street Armory -- haunted house downstairs), but all the info you need is up on the site from last year.
