NYC to DC on the highway, 66.8 mpg

Well, I'm sort of on vacation and had been busy with work...but sometime later I'll have to do an updated highway driving post. Tons of other people have gotten it before me (namely Hobbit), but finally finding it on your own and being able to implement is pretty cool.

66.8 mpg (so about 66 in real life) over 240 miles from NYC to DC
