Giving cachers a second cache to find in case you need an extra reason to hike this far. Placed in honor of Ullii's "The 100-Mile Hike" a challenge to hike 100 miles in 10 mile incriments in 10 different highlighted parks. Nozy is trying to add to the fun,
The Pleasanton Ridge one of East Bay Reginal parks is a great place to hike.
Enjoy!
