You can find reasons to admonish almost everything about the Colorado Rockies—from the mascot to the management. But you must admit, Denver does opening day right. Fans literally paint the town purple as though they are paying homage to Katharine Lee Bates’s famous line in “America the Beautiful”: “For purple mountain majesties.” Fans pack LoDo bars hours before the first pitch, then stroll down to the local diamond—Coors Field. While Dinger is the unwelcome relative at the party, “Take Me Out to the Ballgame” greets your ears like an old friend. Patrons pack the park from the rooftop bar to the outfield concourse in hopes of a home run and a Rockies victory.
