Looking like a local
I stopped at a local place to fuel up, since my gas gauge was running low. As I was pumping my gas, it occurred to me that I really did look like a local -- I had a ten-year-old, cheap American car, very dirty, with a bit of body damage, and my tires didn't even match.
The other weird thing was that, at the level the fuel gauge had been at, in Albuquerque, it would have taken 12 gallons to fill the tank. Up north, it only took 10. When I made calculations based on the odometer mileage, El Caballero had been getting 35 miles per gallon. When I fuel the car in Albuquerque, even if coming right off a trip up north, I only get about 30. The best conclusion I can come to is that a gallon is bigger in Rio Arriba County than it is in Albuquerque.
