Tom Bodett shares the cultures found stretched across America's Southwest with us showing us little bits of stuff all over. For either those looking for a preview of what their own vacation drive may be like or more likely for those like me who never came closer to exploring those trails than my VHS player. Why the travelers were there. What they did there. What effects they had on their surroundings. What effects their surroundings had on them. As much as can be covered in half an hour. How various rivers figured in. And the mountains of the Continental Divide. And even the story of the Gold Rush, too.
