When I lived in California, the last place I worked was at Xerox, R&D, Parc Facility in Palo Alto. The unibomber was active in those days, and he wasn't the only one that Xerox worried about. We had, I SWEAR at least one bomb scare per month, towards the end. And, to make it worse...The firemen would come and search the building, each time. The bad thing was....We were forced to remain in our offices or cubicles, until they were searched. It made me decidedly nervous waiting for them to come all the way down the hall....I was in a corner...till they got to my office. I moved to Chicago and went to work in the Hancock Building. I used to get panic attacks in the elevators with regularity. (This may have been in part due to earthquakes in my past.) Today, nothing could make me go up in a highrise.
