Car bombs were a dime a dozen in the 70's in St. Louis though always intended for individual pols &

and bosses. I had been jogging along the river during a layover in St. Louis about as I passed the Gateway Arch on my way back to my room at the Sheraton Hotel there was a tremendous boom and black smoke billowed from a parking structure next to the hotel with car horns blaring loudly and echoing from the open structure.

I learned later that a bomb had been placed in the car of a politician who had been to a political luncheon at an exclusive restaurant. As I recall he was killed but who ever was with him survived.
