In 1902, a miner named William "Burro" Schmidt began digging a tunnel through a mountain in California's Mojave Desert. He continued, by hand, for three decades, despite that a road was built during that time, and his tunnel came out on a ledge above the valley. You can visit Schmidt's work down a silty dirt road. It's a slidey, sandy journey, but it's so easy in the Chevy Colorado ZR2 that if Schmidt had had one, he wouldn't have bothered trying to make a shortcut. Much like the burros that gave Schmidt his nickname, the Colorado is stubborn and sure-footed....
