I recently ran across this great article on GrindTV.com about the science behind a road trip. So for anyone thinking about taking off this summer and hitting the open road, check this out before you get started. It provides the most efficient way to travel the 48 states with several historical stops sprinkled in along the way.

Enjoy!
