Fans who mix booze and driving with the Rocky Mountain Showdown could face game day in the slammer.

State and local police are beefing up DUI enforcement surrounding the 10 a.m. Saturday football clash between CU and CSU at Invesco Field at Mile High.

"This is always an exciting game and we want everyone to have a good time, but fans need to celebrate responsibly and safely by designating a sober driver," Denver police Capt. Joseph Padilla said in a statement today. "If you choose to drive impaired, you will get caught and arrested."

State troopers will increase patrols along Interstate 25 between Fort Collins and Denver, and help Boulder County sheriff's deputies enforce laws on U.S. 36. Denver police also will be boosting patrols around Invesco Field.

College students representing The BACCHUS Network will be on hand before the game, to educate fellow students about impaired driving by handing out scratch tickets with alcohol-related questions and the chance to win prizes.

In addition, they will distribute information to encourage fans to designate a sober driver or to seek a safe ride home, such as RTD.

"Students talking with students is one of the best ways to remind fans about the importance of having a sober driver or choosing an alternative safe ride," said Drew Hunter, president of the BACCHUS Network, a national nonprofit that works with college and university campuses to promote safe and healthy decisions, including preventing impaired driving (www.bacchusnetwork.org).
