Wait until it starts approaching and averages about $8.00+ bucks per gallon.
It will beat tourism like a drum.
I agree that at that price it will have an immediate effect.
Some peeps are laboring under the misconception that $5 - $6 range is transitory and that things will return to normal before long. So they keep spending.
But to your point...at $8 /gal the cost impact is immediately and painfully apparent when 6 figures appear at the pump. Those long round trip drives are really going to hurt.
(Paying for the necessities is going to get harder and harder, and eat into whatever disposable incomes people once had. This belt tightening is going to ripple throughout the economy making jobs less secure. A big mess in store for us. Elections sure do have consequences.)
