Cache is NOT at the posted coordinates! This cache is placed about 30' east of a cannonball fired into Fort McHenry during the War of 1812, which now resides on a street in downtown Baltimore. It's easy to miss when walking by, but I thought it was pretty neat, so hopefully this cache helps someone else find it. If you can find that cannonball on the map, you can likely letterbox your way to the final hide without issue. The title, posted coordinates, and puzzle are inspired by the cannonball (and how it got into Fort McHenry).

Enjoy! As always, feel free to get in touch if you need a little push. The log paper is quite plasticy, but a sharpie or a pencil will be adequate to sign. Parking is available near the cache site, which is about a two-block walk from the harbor. Stealth required for this one. Please replace with care, making sure it's inconspicuous and secure.
You can validate your puzzle solution with certitude.
