That's how gas was available that day in Catavina. Never pass up a chance to fuel up in Baja, you can see to the right ,further ahead in white and green,  what's left of the Pemex station that is listed on the map. Sure it cost a little more this way. Look at all the work involved. How does he know exactly how much? Who cares...!
