As you walk along the river enjoying the view on the Greenway take a moment to find this Multi-cache. Starting around the Four Freedom Monument at the cords show above, project a waypoint on a line 867.4 feet at 166.5 degrees. There you will find a nano hidden, so bring tweezers and a pen to record your find. This is High muggle area most of the time so great stealth is needed. You will probably blend in as there may be many people chasing little critters with their cell phones
