Where's the furthest you've gone on a road trip?

On May 4th Joey, Josh and Adam, three guys in their 20's, took on a wild venture: to go on one road trip and hit all 48 contiguous states and never stop (except for gas). Josh's father was the original planner who mapped the trip and was going to take the challenge himself several years ago. The trip never happened due to the death of his mother shorty before the journey was supposed to begin. And so the baton, or map rather, was passed on to Josh and his two buddies. The world traveled with them on their blog. The trip began in Boston and ended at the Four Corners (Brilliant!). To make a very long story short here is what these three guys accomplished in FOUR DAYS:
• 7,008 Miles
• Exact time: 106 Hours and 43 Minutes
• Saw 90 cops
• And never got pulled over (Wow!)
• Highest gas price: $4.15
Lowest gas price: $3.45
Showers taken: Zero (I guess ya gotta do what ya gotta do.)
