EL PASO – It is a warm Sunday afternoon and a group of young men has gathered at the University of Texas at El Paso to practice parkour (PK) – the gymnastic art of overcoming all obstacles by leaping, springing, and vaulting. More than physical exercise, parkour is a way of life to its practitioners. Dressed in sporty outfits, they begin stretching and warming up for the workout ahead. A large cloud has just covered the sun and the young men smile in admiration. It’s going to be a great day.
