My wife is watching TV and said gas will jump 15 cents a gallon tomorrow. It looks like gas is going to go through the roof. This could make people think twice about hopping in that SUV and sitting in traffic idling. People might consider the train as a viable option now. Gas has always been much higher overseas and with China growing, I think we might never see gas under two dollars again. They have radar detectors that tell you how fast you're going. Maybe Amtrak should put a digital billboard on a highway that always gets jammed and have the readout increase in price for the gas they are burning sitting there. Metra has standard billboards around Chicago in those type of congested areas. Having a train fly by at the same time next to them helps too though.
