As a part of the 2003 California Ghost Hunter's Conference, Dave attended a special tour of Alcatraz Island. The tour included areas of the prison not included in the regular audio tour. Participants visited areas including the de-lousing chamber, the hospital ward, the shower rooms, and the morgue, led by rangers who have experienced explainable phenomena while working in the prison.
Upon entering the hospital wing, several participants reported different phenomena, including cold spots and head pressure. In the lock-up area of the medical wing, a conference member began to communicate with an entity at the entrance to one of the cells. The member experienced feelings of great fear being communicated by the entity. Following communication with this entity, the antendee experienced pain and bruising in her right forearm, which continued for several days afterward. Other rooms where tour participants reported unusual sensations included the dental suite and the medical shower areas. One participant reported the feeling of being pushed upon entering the powder keg room off the main chamber in the morgue, though no other person was near him.
The rangers told stories of running footsteps where no rangers or tourists could be observed, and seeing people who vanished into thin air upon closer inspection. The tour concluded following the ranger's stories and all participants returned to San Francisco.
