Two people were arrested for drunken driving by Corvallis police Sunday. Only one of them was processed through the Oregon State Police mobile DUII unit borrowed by Corvallis police in anticipation of Civil War rowdiness.

State troopers in the Corvallis office of the Oregon State Police brought in the same Salem-based unit to discourage drunken drivers during Oregon State University homecoming and Halloween activities.

Despite only two drunken-driving arrests, Corvallis police had a busy day on city streets. Between 3 p.m. and 1 a.m. Sunday and Monday, police wrote 17 traffic citations. They also issued 34 warnings. Police arrested a total of 21 people during the 10-hour period, including two arrests for fourth-degree assault, two for violent conduct, seven for being minors in possession of alcohol and six for people having open containers of alcohol.

Lt. Jeff Lanz of the Oregon State Police office in Corvallis and Lt. Mark Potter in the Albany OSP office both said it was a relatively quiet weekend on area roads - unexpectedly quiet considering the number of people in town for the Civil War.

That mirrors state statistics for the entire Thanksgiving holiday weekend, which police calculate from 6 p.m. on Wednesday, Nov. 26 until midnight Sunday, Nov. 30.

Lt. Greg Hastings of the OSP headquarters in Salem said two people were killed in traffic crashes during the Thanksgiving weekend, but that was half of last year's fatality total and the lowest number since 1999.

Both fatalities this year were on Interstate 5. The first happened Thanksgiving night near Milepost 278. The second was Sunday night in the Portland area.

Not in the 38 years that the Oregon Department of Transportation has been tracking holiday fatality statistics has there been a Thanksgiving weekend without a single traffic fatality. The worst years were in 1973 and 1996, with 11 fatalities each.

Hastings said this year's numbers are subject to change as more information is compiled and reports from Oregon law enforcement agencies are updated.
