A full size Suburban down Battle Axe and Walnut Canyon roads. He curled the edge of a running board but not so you'd notice, other wise, in and out safe and sound. http://hikearizona.com/photo.php?ZIP=253471
We were down there checking out a potential river crossing site. We saw two thru-hikers. I've seen at least one, and one day three, while out on the AZT this spring.
