This cache is NOT at the posted coordinates.
To find this cache you will need to complete the Avery Adventure Lab. The adventure lab will take you on a tour of Avery Park. It includes many of the fun sites of the park like the steam engine, rose garden, playgrounds, kiosk with historical information, and wooded trail. The route is a little over a mile to walk or parking can be found close to each stage. The last journal entry of the adventure lab will provide you with the final coordinates for this bonus.
BYOP. Please tuck the cache away carefully after signing the log. Thank you!
Enjoy!
