In the late 1980s we lived in a housing development in SoCal. (If you ever saw the movie "Poltergeist 2", that was our street -- our house is clearly seen during the opening credits.) The neighbors on the corner next door were pleasant enough, but husband & wife would often go away on the weekend and leave Junior home alone. Which meant posters announcing "PARTY!!!" went up at the local high school. Those were some pretty spectacular events.
Meanwhile, during those same years, President Reagan's two young grandchildren would sometimes visit and stay overnight at our house (long story). This was shortly after the Libya bombing and Khaddafi's overt threats against Reagan's children and grandchildren, so the Secret Service was not playing games. When the kids were at our house there would be two unmarked Mercury station wagons parked at the curb in front of our house all night, and guys with mirrored sunglasses, earpieces and guns sitting in them. We had to leave our front door unlocked all night so they could use the bathroom.
One magical weekend the two events coincided. For some reason Junior's party next door was much more mellow and subdued than usual. Maybe the guys with sunglasses sitting out in the station wagons all night had something to do with it ... ?
When the neighbors returned a couple of days later they came to our door and asked delicately if we had called the police on their son. We smiled and said, in all sincerity, "No ... those were Federal agents."
(For what it's worth ... I don't know how things are now, but all of the Secret Service agents we dealt with in those days were courteous and very professional. The Secret Service then was part of the Department of the Treasury; now protection services are part of Homeland Security.)
