Check out this video posted on a WA state wrestling message board. It's the entire 1968 NCAA finals that were in Rec Hall that year. Two notable matches were Dwayne Keller vs Rick Sanders and Dan Gable winning his first NCAA title. I was there when this happened. I'm guessing a few other old timers posting here also saw this live.
