Rough Roads. Travel At Your Own Risk.
This is not the most welcome sign for traveling on the gravel roads of the Mojave Desert, in the state of Nevada. This is in the Desert National Wildlife Range, which, furthermore, has much of its area lying within the Nellis Test and Training Range [_*_], and is on the edge of the Nevada Test Site [_*_].
This picture was taken near the Corn Creek Field Station, on the junction of Alamo Road and Mormon Well Road (see workshop, with the sign and distances to several locations; it has also a shot of the car).
In the other workshop you see two aliens puzzled over a Nevada road map.
Location in WikiMapia: 36.4383484, -115.3574431.
After reading the comment of Barbara (baba_flies) about wild shooting on road signs, I posted a workshop with a No Firearms sign.

After reading the comment of Barbara (baba_flies) on the primary post, about wild shooting on road signs, I remembered this photo, shot nearby.

This is near the primary post.
