east of the stadium along Kimball (the road on the north edge of the stadium), there are public lots. Thats where we tailgated in '06, and will likely be again if we come saturday. It was a good time, as there were a TON of ISU fans there, and the KSU fans were friendly. Be warned though, that they graze sheep in these lots most of the time, and the locals call it "Sheep Lot" (like we have "grass lot"). My buddy became quite ill after the 2006 trip, and we blame it on the sheep... Also, keep the booze in cups and you'll be fine. The tailgating scene is decent, the best I've seen in the Big 12 after ISU, but its still a ways off from being Ames quality. Still a good time though.
PS, Cardinal&Gold11, your sig made me **** myself laughing. Sunny is the best!
