The whistle or horn going off at 1pm on Saturday afternoons at the P plant? Maybe it was a siren, I do not know.
Yes! Siren. Not really an 'old' timer but remember that 1pm siren. Attended my first game at Clemson in 1973. Texas A&M. We lost....15-30. Mitch Tyner had an 82 yard punt. A&M had a RB named Bubba Bean.
Volunteer Fire Departments will test their sirens and response times on Saturdays at noon. After returning from Desert Storm and enduring several alarms for SCUD missiles a USMC buddy and I were fishing up in NC one Saturday when the test siren went off. By then it was second nature, we both bailed over the side of the canoe and laughed all the way home. It was a wet ride.
I grew up in Clemson. Graduated Daniel High School in '85 and Clemson in '89. I remember growing up hearing the Saturday 1PM siren. I don't know why it went off or when the practice/tradition stopped, but I distinctly remember it.
It was a 1 pm siren from the P-Plant. I lived in A-804 in '73, and A-904 in '74 - these rooms were right below/above each other and faced West, directly towards the P-Plant, with a beautiful view of Death Valley and Lake Hartwell. I was in "Architecture" and unfortunately missed many a game on Saturday due to sleeping in, but that siren always woke me up, or certainly caught my attention.... I now live in Spartanburg (since 1978), and every Saturday a city-wide siren goes off at 1 pm, as per tradition, regarding the shift change in the textile mills.
I also remember when an acetylene tank exploded in the P-Plant and landed in the middle of the field of Death Valley - no injuries I recall, but the blast was tremendous.
My freshman year was 1969 and I remember the University Police Dept. making announcements to move your car by 8am on gameday mornings and the Marching Band starting their morning Practice for the game at 8am under F overpass. That helped cure a hangover.
