I am. I have been following ISU since late 60's, early 70's. I expected replies. Some just can't get over themselves. Gene Mack, Jack DeVilder, Bill Cain were playing when I started listening.
I went in 2016 and 2019. Tickets were cheap. NCAA tournament games a rarely sold-out. Not enough time to make plans if you have to travel. Obviously if Iowa or ISU would end up in Des Moines it would sell out, but not with any other teams.
