INSTRUCTIONS: The city spreads out before you. Rushing from point to point, lit by the slow strobe of fluorescent buses and dark streets. Stumbling into situations for a stranger's signature. Fleeing unknown pursuers, breathing hard, admiring the landscape and the multitude of worlds hidden in it.

For one night, drop your relations, your work and leisure activities, and all your usual motives for movement and action, and let yourself be drawn by the attractions of the chase and the encounters you find there.

A thrilling fifth-anniversary pursuit through San Francisco. If you participated in this Journey in any way (as a player, chaser, or volunteer), please tell us about your experience.
