When I had my PSD, I once paid $4.68/gallon in July 2008 in Natchitoches, LA. Hopefully prices will start dropping soon for both diesel and gas. The prices are bad enough for everyone, especially those driving 18 wheelers. I also remember in the mid 70's when I had a school bus for awhile (73 Ford B-600) and put 25 gallons in every other day at 55 cents a gallon (of course we'll never see those days again).
