Went last year, didn't know what to expect and was AMAZED. I've been waiting all year for the next one. Plenty of cool bikes, both in the show and parked outside. Really laid back people, sort of a gallery/art show vibe inside, and best of all, once the sun went down, Free Beer and live rock music! And you get to ogle hipster Brooklyn chicks!
There are very few bike shows in the NY/NJ of this caliber, I'm definitely going this Sept.
