You bet your ass it is!
Someone once told me that the many vertical gouges one sees adorning the fall-lines on the blasted shale mounds on the Navajo reservation north of Flagstaff are the result of similar recreation. I hope it's true. It would certainly be an excellent way not to grow up a whiner, taking high-speed, face-first diggers into the Chinle Formation, picking shards of petrified mud out of eyes and teeth, and cheerfully sprinting back for more.
Sledding anyone?
