Who knows what an all Hwy trip would look like.
Man is it hot ...
My trip to work is 10miles...and there is on a very rare occasion that the road opens up...and so does my 6...140 maybe...
that probably kills my MPG...
that and i'm like you blackjax...i only do the speed limit 98% of the time....but i get there very quickly.
