I was amazed at the difference in some parts of the country-Last Wednesday I flew to Atlanta to take my DS to visit Clemson. On the way to the airport I paid $1.65. When I rented my car in Atlanta they said I could pre-pay gas at $1.51 and bring it back empty. Since my return flight was at 0600 I bit-then saw that it was about $1.45 in Metro Atlanta and $1.33 in the Clemson area. no big deal and I only used one tank-then when I got home it was down to $1.59-I could have gotten to the airport with out filling up so I screwed up twice in three days.
