(my distances were greater; I had to use a bit of subterfuge and some cash of my own to keep idle time costs lower: the quarterly bonus more than paid it. I never won, but I never got reprimanded either; none of which are your worry).
You can find a 400+ mile roundtrip that can be taken over a days length with appropriate fuel stops, and, over a familiar highway, learn what your highest possible mpg may be (given road, load, conditions and weather) that will consistently report the "racetrack numbers" (no warm-up or metro traffic involved). The more you use the route -- the more easily the mental map comes to mind -- the better will be your judgment of your efforts.
And here's beer numero tres.

I didn't follow that til I read it again, you make a good point. This rig has a big, very efficient radiator that takes forever to hit operating temp. From now I'll be sure it's up to temp before I fill it and hit the road. The station on Ironwood in AP is easily 5 miles from the freeway with at least 5 or 6 lights and I always get caught at least twice, one way. I need to find a station right off of 60 for this to be more accurate. Thanks. Oh yeah, I'll take you up on the cerveza also.
