There was one spot on the Blue Ridge Parkway where I had ridden about 120 miles and started panicking since there wasn't any gas for at least another 20-30 miles. Somehow, I eventually coasted into an Exxon and all I could think about was a certain Seinfeld eppisode where they see how far they can drive with the gas light on. Needless to say, I'll be buying a 2.5 gallon fuel tank and strapping it to the back for future long distance trips.
