This isn't your father's Conoco station -- unless your father is Jackie Chan. In addition to the usual independent, urban convenience-store hodgepodge of noodle bowls, outdated hair dye, magazines, 3.2 beer, adult diapers and miniature pipes, the sign that greets drivers heading out of downtown on Speer Boulevard promises "souvenirs." And how! Nothing says "I've Been to Denver" more than a jade bracelet, a pair of brass knuckles, an elegantly engraved gutting knife or a throwing star. Okay, maybe a beer-mug magnet, but this Conoco has those, too.
