I was at Camp Tien Sha in 70-71 with Tien Sha Security then later with the Naval Support Facility Police. Pulled guard duty at Philco-Ford for several days. It was abandoned when we were guarding it. I also had been to the transmitter site and the club near there. Quite a hike. Tien Sha Security was responsible for patrolling from Covered Storage to Deep Water Piers. Later, the NSF Police patrolled the same area, but also patrolled the villages along the highway.

By the way, did you ever live in Illinois?
