Greetings,
Nick & Ivy's first official Geo. No better place to hide it than the place her and I first met! Good Ole' Roosevelt Field Mall. Please note we did not meet in the stairwell, but we did meet inside the mall. 
Once an airfield that served as a take-off spot for Amelia Earhart it not serves as the largest mall in NYS. if you're lucky you can catch a decent sunset view from the top floor of this very parking garage.
It's a nano, and it'll take a few steps to find it. But it's there (hopefully). Plenty of parking, after all, it is a parking garage. Good luck!!
This is accessible even if the mall is closed.
