Two guys completed the drive from Nebraska to Aspen, Colorado on a mini bike just like Harry and Lloyd in "Dumb & Dumber."
Ari Henning and Zack Courts have a motorcycle blog on RevZilla called Common Thread. They decided to build a replica of the bike used in the movie and drive it 400 miles along the same route. It took three days and it had its share of issues, but they made it happen.
You can watch footage from their trip below:
