Steve Hayes, who starred on the 1977 ISU team that made it to the Final 8, has been posting some great nostalgic photos from that season on Facebook. Below is a link to a shot of the Minidome (now Holt Arena) in its old configuration, with the basketball court in the middle of the field and fans using both sides of the football stands. This is what it looked like when it hosted NCAA first round games back in the 1970s. Hard to believe now, but Holt (the Dome) was one of finest facilities in the West in those days.
