Yesterday, I took a trip to a friends farm where I hunt and ride horses. It's 150 miles round trip over rolling hills, thru a couple of smaller towns, a small city and only 40 miles of interstate. I drove without cruise control and kept my speed between 5-10 miles over post speed limits. I averaged right at 29.9 when I finally made it home. Many times the average would be in the 31.5 range. In fact until I climbed the long, steep, winding hill to get to my house it was averaging 30.5 MPG.
