"Historically, the Orange Krush has used elaborate disguises to gain access to away games. In the spring of 2005, 100 members posed as "Youth Action", a fictitious Chicago-area youth-group, to get tickets to a game at Michigan. The Krush was offered a tour of the Crisler Arena, but declined. Instead, they were also offered a photo opportunity with then coach Tommy Amaker, which the Krush took advantage of before the game. The Krush did not reveal themselves as Orange-clad crazies until just before tip-off.[6]
In 2006, the Krush traveled to Minnesota and purchased student-section t-shirts to disguise themselves. After repeated successful trips, many Big 10 ticket offices imposed restrictions on tickets for Illinois games in an attempt to quell the invasions. In the spring of 2007, the Orange Krush posed as a Chicago-area Penn State Alumni organization and were able to get prime tickets right behind the basket, directly adjacent to the Penn State student section. They invaded Michigan in 2008, Purdue in 2009, Iowa in 2010, Minnesota in 2011, Nebraska in 2012, Northwestern in 2013, and Penn State in 2014 with about 150 members participating every year. Opposing Universities have imposed restricted ticket sales for games against Illinois because of this.[7]"
