Gas To The Future

I’m going to write a novel, loosely based on the classic trilogy Back to the Future. But, instead of a complex formula and tactics to find out when the lightning will strike the clock and provide the energy to start the Dolorian … the characters will map out what times of day, locations and periods when gas prices drop a statistically notable amount. It will be like the iPhone app, Gas Buddy, but instead of mapping out current prices arranged by amount, it will also be arranged by time. 

The point?
