This is the first bit of Long Way Round, a documentary filmed in 2004 following motorcycling buddies Charley Boorman and Ewan McGregor in their journey from London to New York. Their trip took over three months and covered approximately 19,000 miles, all on BMW 1150GS motorcycles.
My good friend Matt and I have a continuous discussion about circling the country on our bikes, and this documentary is a powerful inspiration for us. He's already done something similar when he and one of his motorcycling friends from Louisiana rode the Trans-America Trail. Check out their ride reports here if you're interested. It was quite a ride.
Even if you don't have interests in motorcycling, this is still a wondrous journey to watch.
