This is a bonus cache for the Historic Route 66 Adventure: Helendale to Oro Grande, CA
"The cache is not at the posted coordinates"
Somewhere along this adventure, between Oro Grande and Helendale, hidden, is a cache.

You have two ways of claiming this find.
Option 1: this will require that you use the Geocaching Adventure Labs app onto your mobile device. The coordinates could be posted somewhere in the description or information of your stops along the way. I would recommend this option in completing the Adventure Lab.

At times, this could be a busy road. Be careful pulling off and onto the road when visiting the waypoints. The cache is off the main road along a well maintained dirt road, most definitely 2-wheel drive safe. Keep your eyes for any critters especially the long slithering types during the Spring Summer months. I heard me a yelping coyote out here.......
