$4 a gallon on the horizon?

Time to start walking more. Thankfully, I live in the city where mixed-use zoning isn't an endangered species as it is many of Milwaukee's suburbs.

From CNN Money:

"There's no question gas will hit $4 a gallon," Ben Brockwell, director of pricing at the Oil Price Information Service, said. "The question is how high will it go and how long will it last?"

OPIS tracks wholesale and retail oil prices and provides pricing information for AAA's daily reports on fuel prices.

Brockwell said with gasoline prices now exceeding $3 a gallon before even reaching the wholesale level, it "doesn't take a genius" to expect retail prices to hit $4 a gallon soon.

"Consumers haven't seen the worst of it yet," Brockwell said.
