This is part of the Brooklyn Heights Geocache Project.

Thank you for taking the time to find this geocache and travel here. This one doesn't get a ton of visitors, and is not in plain sight meaning it probably is there. If you would like something to do nearby, you can walk down the hill to Borooklyn Bridge Park and visit Swing Valley, Slide Mountain, or the Water Lab in the summer. Around Spring 2025, I will try to place more caches nearby in the summer and reactivate the nearby ones. Good luck and have fun!

For those of you failing to understand the hint, answer the question using whatever tools are at your disposal.
