20 cents in 4 days

When I ride to work in the morning there's a Tower gas station the has a big bright LED display for its prices. Thursday I saw the price for regular gas at $3.99. This morning it was $4.19. If Peak Oil hasn't already hit, we're pretty damn close. People are talking about gas prices from $7 to $15/gal by the end of the year. Whether it goes up that quick or never comes down any remains to be seen, but the days of cheap gas are over.
