Never Drive Through the Mojave Road Without a Full Tank

There's a mailbox standing in the middle of 1.6 million acres of California desert, roughly seventy miles from the nearest gas pump. Run dry out here, and help is hours away. It sits on a road with no number, no signs, and no pavement — 138 miles long, missing from state highway maps, and older than the United States. The U.S. Army once patrolled this line with camels. A railroad killed it. A fake doctor stole its best water for thirty years. A Navy physicist brought it back from the dead. And none of that is close to the strange part. Start with the practical question, because the practical question is real. The National Park Service tells anyone attempting the Mojave Road the same thing, in more or less the same words: carry water, carry recovery gear, travel with another vehicle, and do not start without a full tank of fuel. Not because it's a scenic suggestion. Because the road runs 138 miles from the Colorado River near the Nevada border to the Mojave River near Afton Canyon, and in all of those miles there is not one gas station. Not one paved stretch. For long sections, not one bar of cell signal. Soft sand can cut a four-wheel-drive's fuel economy nearly in half, which means the gauge drops faster than the map moves. The full tank isn't advice. It's arithmetic.
