i put my 250 in already today...
the key to a happy commute is drive at night
when noone is on the roads
have a good one and be safe
look out for demagnetized cows falling from the sky
You can build-up fantastic MPG ratings that way, too. I am a night-owl, so I tend to drive in late (great boss!) and leave late, so I try to sneak in right after morning rush hour and navigate my way home, hopefully right after the big go home crunch.
