Cadillac Owners.com First National Meet
Des Moines, Iowa Ñ May 18-20, 2007

gdwriter's Road Trip Photo Journal

Since I have to live on a very tight budget, I needed to know what I could expect to spend on gas for the trip. Using my itinerary and information from Gas Buddy.com, I calculated amount of gas I would use driving through each state at an assumed average of 23 MPG, multiplied by each state's average price.

Below the estimate are the actual results from each fillup. I'm surprised--and pleased--at how close the actual results came to my estimate, a difference of just 2.82%.
