Gas is around $4 a gallon here. I remember my dad buying gas at 25 cents a gallon.
As for diesel, back in the 70's during the gas crisis, everyone started buying diesel burning vehicles because it was at least a buck cheaper. How times have changed.
The gas shortage here in Cali was so fucked up that we could only gas up on even or odd days depending on the last digit of our license plates. I know you guys are going to call BS on this, but its the God's truth.
