I also contacted Cyclone Athletics regarding a whole bunch of comments in different threads about whether or not this is a "Gold Rules" day (they usually print it on the season tickets, and advertise it on FB and elsewhere). I was told that although this game wasn't "officially designated" as a Gold Rules game, KU has typically been a Gold Rules game in the past and they wouldn't mind at all (hint, hint) if there was a word of mouth campaign to get everyone wearing gold. The gameday shirts that are being distributed are gold also, I believe?
