This cache is not at the listed coordinates. In order to find this mystery cache you will need to start at The Other Boxborough Library. Inside The Other Boxborough Library you will be provided with the coordinates to this cache. However, the coordinates are not provided on a traditional printed sheet - you will need a compatible Garmin GPS device (see details below) to download the coordinates and hint from the Garmin chirp beacon located inside the cache.
The final is located at one of my favorite spots in Patch Hill.
This cache requires special equipment. In order to find this cache you must have a Garmin Oregon (except 200), Dakota 20, GPSMAP 62 or GPSMAP 78 running the latest software which supports Garmin chirp. See this page for details on how to use chirp and update your GPS.
Thanks to Hermit Crabs for the cache container. This is the old Random Multi final.
Congrats to Nordymogul on the FTF
