The posted coords will put you in the middle of the intersection of 87th and Lisson.
DO NOT GO IN THE STREET TO LOOK FOR CACHES!!!
None of the cache stages are there, but you can find a physical cache at each of the four corners of the intersection if you just stop and look. All of the first four stages are within (approximately) 10 feet of the sidewalk.
This is a high traffic area so try to be stealthy when necessary.
Stages may be found in any order. Assemble the clues from each stage and use a device we expect most people will have with them (or can easily borrow) to determine the location of the final stage.
BYOP. Bring your extraction tools. Another simple tool is also needed, but you can improvise if you don't have one with you.
