It may be overcast and rainy in Denver today, but there's at least one sure sign of summer on view: Gas prices are climbing like Clint Eastwood in The Eiger Sanction. According to the American Automobile Association, the price of unleaded has risen 38 cents per gallon in a month, to an average of $2.39. It's still possible to find lower prices: At this writing, the bargain roster at DenverGasPrices.com is topped by a Costco in Aurora, where a gallon goes for $2.25, followed by a Gas 4 Less in Wheat Ridge, at $2.26. The best bargain in Denver proper as of Sunday: a Diamond Shamrock at 4498 Sheridan Boulevard, with $2.29. But these differentials only pay off for folks relatively near the stations in question.
