Some people would have you think that you need a Jeep to collect the caches along this unimproved dirt road, but don't you believe it! There are plenty of places in the world where a Jeep would be considered a valued tool during a cache run, but the caches out here can be collected easily enough, without the use of that particular tool.
As the sign says, the road ends 2 miles ahead (once you leave the pavement), and the hide location is a little farther in to the desert, past the end of the road.
