Ames police are gearing up for what's expected to be 60,000 visitors this weekend as iowa state takes on northern iowa to kick off the 2017 college football season. Cmdr. Geoff Huff says the first football game is usually busy regardless of the opponent, but having two in-state teams playing means roughly twice the fans. According to the Iowa Department of Transportation, the main area of traffic concern is the westbound exit at the Interstate 35/Highway 30 interchange, and the south Dayton Rd. off-ramp.
