Here some pictures from my trip on the way up cruising about 80 avg speed. I did draft a big truck for 80 miles of the trip at 65mph this was a jump when I could not resist speeding
Here is the tank 2 days later and I still have a little more to drain. I still have about 20-40 miles left I think! We'll find out tomorrow.
looks promising but I may be getting 30+mpg.
