A sign at a gas station shows the price of gasoline to be over $4.00 a gallon in Detroit, Michigan June 9, 2008. The national price for regular, self-service gasoline jumped 6.3 cents over the last week to a record $4.04 a gallon, up 96 cents from a year go, the federal Energy Information Administration said in its weekly survey of service stations. Pump prices are rising because of expensive crude oil, which reached a record high of just over $139 a barrel last week. REUTERS/Rebecca Cook (UNITED STATES)
