Achieved more than 66MPG with optimum tyre pressure.
Pissed off truckies in truck lanes which enforces 55MPH limit.
One car has fingered one me from window
Too many cars passed me and makes me wonder. How can they voice their complaining on gas prices yet they drive too fast. Can't have in both ways!
CHP checked on me from patrol car for around 20 miles.

Will I do it again with $4 gallon. YES!
