Great Mapquest story: my two friends and I were driving from Gainesville Fl to Tuscaloosa, Al to visit another friend in college. I was in charge of the ‘quest, and we had the directions set on when to light the 6 blunts we rolled for the drive (aligned with the longest periods without having to turn, 70+ miles on the highway, etc).
Well, I missed the 0.2mi immediate exit before the 125mi straightaway and lit that next blunt. Long story short, we went like a hundred miles in the wrong direction because I told him we were good for a couple of hours.
