Also, be sure to check out 100LL.com. I've had great results finding cheap gas and its simple to use. Type in an airport ident, lets say KATL, and click search. Scroll down towards the bottom and it will list other nearby fuel prices within 100 miles using your search airport as the center of the search radius starting with the lowest. I'm planning a trip to Denver in August. I plan to stop near the haplfway point which is Joplin Mo. I plugged KJLN and hit search and found that gas at Monett, Mo is $3.40. And since I plan to stop for the cheap fuel as much as I can, this site works well for me. Just my 2 cents...
