Contrails of sweat arc through the air as a football player slams his opponent into the wall, the momentum carrying him over the four-foot barrier and nearly into the nacho-laden laps of a family of four. Fans leap to their feet and pump their fists to a chorus of “Who let the dogs out? Woof! Woof!” With a triumphant grin, the airborne player vaults over the wall and plants his feet firmly back on the green Astroturf as a parade of silver-clad women shimmies into the end zone. Football is the main event on this Friday night, though religion is a definite subtext – with a Bible giveaway, a Christian concert, and, controversially, football players wearing jerseys with biblical references.
