A pretty typical American summer vacation is loading up the car and going on a road trip to see some of this nation's history - Washington, D.C. or that harbor in Boston, for example. If you're a little more concerned about America's future, take a page from the video-happy McCullough family that's planning a trip called Our Renewable Nation. Long-time AutoblogGreen readers will recognize the family as the one's who brought you Darth Vader's Hummer and other videos.
