Gas prices are expected to sky rocket very soon. After a fire broke out this past Monday night at a Chevron Refinery in the San Fransisco bay area, analysts urge drivers to buy their gas now. Bob van der Valk, petroleum industry analyst, has over 50 years of experience in the oil industry. Valk predicted gas prices would rise to $4 during this week and $4.50 by Labor Day. Ridiculous right?!!?
