It’s always good advice to avoid drinking and driving. Especially between now and New Year’s Day. The Walhalla police have announced they’ll be on the lookout all this weekend for drivers under the influence. According to Sgt. Aaron Alexander, you can expect to see mandatory-stop checkpoints throughout the city. Alexander says his department will be doing its part in this year’s Sober or Slammer saturation effort that began statewide December 13 and will continue through January 3.
