Ghost Patrol
Ghost Patrol can refer to some puzzle hunt events in the San Francisco bay area or the people who run these events.
Each round in a Ghost Patrol event involves learning some facts about a restless ghost by solving puzzles; then puzzlers can help the ghost rest by solving a last puzzle.[1]
Members of Ghost Patrol Game Control formed Trivium Games, an escape room company. They have a Ghost Patrol[2] escape room, a Top Escape Room.[3]
