One other thing i notice from the old photos of Clyde Williams and early JTS, is the total lack of Cyclone gear. No jackets, etc. Some of the goofy old yellow hats with ISU on the bill, but that's about all. Times have changed. One thing I do remember as a freshman in 1975 is being to take practically anything into the stadium. They only prohibited glass bottles. We would take empty plastic gallon milk jugs and fill them with keg beer and bring them in. No problem. You could bring food in, and even smoke tobacco products if you were so inclined.
Back in the Johnny Majors era (before I was transferred to the Detroit area), I had season tickets and sported gold bell bottom pants to go with a gold hat. Only had Clyde Williams Field to show them off though.
