After the first 200 miles I filled the tank and did the calculations to determine the mpg I was getting. Yikes! I only got 7.4 mpg on that stretch. I immediately thought about my budget and how far I could realistically travel averaging 7.4 mpg. Then the light bulb above my head flashed on! How much better would my gas mileage be if I drove a little slower? (Duh!) What was my hurry anyway? I have nothing to do and the rest of my life to accomplish it!
The next 200 miles I tried to stay around 55 mph with the occasional 60 mph to pass a truck or another RV. My mileage improved to 9.5 mpg. What a relief! As I traveled north, the scenery improved and it was much easier to take it slow and easy.

With scenery like this to inspire me, I averaged 50-55 mpg on the third leg of my journey and achieved my ultimate goal of just over 10 mpg!
