It’s not just the weather heating up this weekend. 

This Sunday at 10 a.m., the FDNY’s 2015 calendar models will be doing what they do second best: taking pictures with fans in Times Square (with a fire truck, and possibly other photo-ready accessories). The appearance is to debut the Hard Rock Cafe’s new collection of FDNY-branded merchandise to benefit The FDNY Foundation

On a less prurient note, Commissioner Daniel A. Nigro and first responders will be sharing their personal experiences during a presentation at the restaurant.
