No kidding - at my previous job (oh, at least a decade ago) I had a project in Stockton at the electrical substation on the south side of Church Street between Center and El Dorado. I walked around the facility the first morning checking our USA marks (Underground Service Alert). There was a dude sitting against the perimeter wall with his eyes closed, head tilted back, and a needle sticking out of his arm. I did NOT go check to see what his condition was. A bit later in the day, someone was having some kind of fit outside the entrance gate and an ambulance rolled up to help her out.
