UPDATE: Dr. Hamilton provides an excellent discussion and a weekly graph (as opposed to 4 wk average from DOE).

Demand for gasoline usually falls after labor day, but this still represents a 6% drop in demand for the comparable week from 2004. Prices for "Retail Average Regular Gasoline" dropped about 3% to $2.96 from the record $3.06 the previous week. Based on futures prices for unleaded gasoline, it appears prices will drop further this week.
