The team of three friends has, over the years and across thousands and thousands of miles, proven to be excellent travel companions. After testing their mettle bouncing across the wilds of Southern Africa in two off-road vehicles, and having published books about it, it was time to test the wilds of Western USA. This is an account of their momentous 4,000-mile, two-month adventure across seven states: from Denver, Colorado, to Mammoth Lakes, California. They have been from 11,000 ft to minus 200 ft, from 25 F to 109 F. An unforgettable journey where each park impossibly managed to outshine the next.
