At present we are in Grand Canyon National Park and expect to continue to Zion NP the 13th. We have driven almost 1100 miles (1760km) and so far our gas mileage is better than expected. The first three tanks of gas have brought us over the Sierras and through the heat and still we have done 16.2 MPG (6,8 km/L) â€“ this is pretty good, but we also tried to drive carefully pretty much all the way.
Below is a map of where we have driven so far. A bit of driving is missing because a) I forgot to turn on the GPS logger and b) it went out of power while driving.
