What is an adventurer to do when it comes time to celebrate that 40th birthday? If you're Dave Cornthwaite, you set off to travel 40 miles using 40 different modes of transportation. If you're familiar with Dave's past expeditions and adventures, this won't come as a total surprise, as he's always looking for new ways to explore a destination. Of course, this video comes with his usual dose of charm and humor too. We should all welcome our milestone birthdays with such enthusiasm.
