If you've ever been to Grand Canyon West, you've likely traveled the winding dirt road known as Diamond Bar. I start down Diamond Bar at about 6:30 this morning, and I turned around about 8 miles down the road at about 7:15. The rain had made the road rough up to that point, but I came across a rut in the road about a foot and a half deep. I had serious doubts that the Corolla was going to make it out the other side.
