I've looked at this little 2-track many times, thinking it might be a good place to hide a cache. The road is here to allow crews access to the nearby billboards when they need to change the sign.
Warning - be sure that you go WEST from Francis Rd, not east. There's a 2-track going that way that is used to access another billboard on that side of Francis Rd. However, that road is rutted, muddy, slick, and a lot harder to get through. I tried it in wet weather with my 2WD truck with summer tires, and spent some time getting out after I almost got stuck. I wouldn't go back in there again unless it was dry weather, or I had 4WD.
