Denis Menke was a hard-nosed, quality baseball player from Bancroft, IA, who was "in the news" in the early '60s for his performance on the baseball field, and if memory serves correctly, was a star on a semi-pro or similar team from that area.
In 1962 he was drafted by and played for the Milwaukee Braves, later to become the Atlanta Braves, but before he ever got to that level he had gained enough attention that Principal Bill Mansur invited Phil Johnson and Larry Holstad to attend a game that Menke was going to be playing in. They agreed to join him and off they went.
As they were driving south on Highway 69 somewhere in the vicinity of Lake Mills or Forest City, the highway, as the Google streetview above shows, takes a bend to the left, and a stop sign is there to manage the merging traffic.
Speeding along at 55 or 60 miles an hour, and busily engaged in conversation with his young riders, Mansur went right on through the stop sign. And seemed not to notice it until he was several hundred feet past it, at which point he said, "Boys, did I just go through a stop sign?" Dutifully, Phil and Larry said, "Yes, you did."
Mansur brought the vehicle to a stop, put it in reverse, and backed up whatever the distance was, a quarter mile, perhaps, one arm hung over the back seat so he could see where he was going, until he was back properly positioned to make a stop. Which he did, and then proceeded on down the highway he had just left. No harm, no foul, I guess.
The details of exactly where it happened or how far he drove are fuzzy to this writer, but the story itself is accurately portrayed, and the Iowa landscape you see above is testament to the possibilities - in fact, do you see a stop sign? Neither do I.
