Charles,
My personal observation is also gas prices rise a lot faster at the pump than they fall due to wholesale price changes. If any fuel dealer pays X dollars and has a full tank sitting underground for <month, and he's low volume, he's a lot more likely to raise the price if the wholesale price goes up,irregardless of the price he originally paid.
The good news is everybody's truck should have relatively low prices for gas/diesel through this summer , and if you drive home slowly after LTA 2010, you'll get decent mpg as it's downhill to everywhere USA. Except where SSS Jon W lives in Uppa US.
