You have to take the series back to the early 60s for ISU to have an above .500 record vs K-State.
LOL, I can tell you that the old Cat fans that I know were more concerned in the 60's about nailing as much "free love" ass as the could than they were about football that wasn't even on TV.
KSU fan in the 60's: "He guys, let's go smoke some weed with these chicks and have loads of sex with them."
ISU fan in the 60's: "Nope. We are going to sit in the dorm room and listen to the AM broadcast of the ISU football game from the Story City radio station."
