Throughout the great State of Colorado this week, you don’t have to look far to find people rocking Peyton Manning’s number 18 Denver Broncos jersey—and for good reason. The Sheriff and his Broncs are gearing up take on the heavily favored Carolina Panthers in their second Super Bowl appearance in three years, which is somewhat miraculous when you consider that Manning missed a large chunk of the regular season due to injury.

But there’s one area of Colorado, the Greeley-Evans School District 6 to be exact, where Manning jerseys will be nowhere to be found this week. The Greeley-Evans School District oversees 25 schools that cater to over 21,000 students, all of whom have been banned from showing support for Manning. Why? For fear that students will be viewed as members of the 18th Street Gang, which Wikipedia describes as “a multi-ethnic transnational criminal organization.”

Greeley-Evans school district spokeswoman Theresa Meyers told The Tribune, “Gangs use those items of clothing for a few reasons. They use them to recruit and they use them to intimidate.”

Even weirder? Rocking Cam Newton’s number 1 Carolina Panthers jersey is OK, since it has no ties to gang activity. Something tells us, though, that wearing Newton’s jersey this week in Colorado would be an equally poor choice.
