Despite the "half of a mile or so" they think this idiocy saved them, I measure on Google Earth, and it actually saved only 0.15 miles vs. staying on the road, and surely took way more out of Rob (and especially the poor sap who keeps having his bike tumble down on him!) than taking the road route would have.
Later, they were so concerned about minimizing the mileage that they took the RV off-road and got it stuck in the sand.
Then, between Kirtland and Farmington NM, they're so unconcerned with mileage that in quick succession, Rob runs off-route over to a cafe, an erotic toys/video store(!!), and a Dollar General parking lot. The craziest one is the Dollar General, where he *backtracks* west out on the road through the driveway they came in on, even though there was an obvious driveway out the south side that would have saved him 0.07 miles (not to mention even more-direct unpaved terrain that would have been far easier to run on than that scramble in California).
The confusing thing here is that it's pretty clearly not the RV creating the track, which would be the obvious explanation. The GPS track looks very much like a running track, particularly since most of it is on the wrong side of the highway.
So I'm trying to figure out, are they just that dumb? Or is something else going on here? Like maybe that was really Dustin on the bike?
