My average was 70.3 after a long road trip from Oregon to SE Texas once, only stopping for gas. If you idle a lot or sit at long lights in traffic you will have lower averages than the guy that is on the freeway more.
Someone needs to reset their average, do a run on a mile strip and post an average of 125. Would make a neat photo for the mancave?
Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "Holy shit, what a ride!"
