Putnam County police agencies are participating in special efforts this weekend to bring awareness to the dangers of impaired driving. The statewide STOP-DWI High Visibility Engagement Campaign started today and will end on Tuesday.  Putnam County Sheriff Kevin McConville says the Fourth of July extended weekend is historically a deadly period for impaired driving.  He says highly visible, highly publicized efforts like this aim to further reduce the incidence of drunk and impaired driving.  There's a mobile app called Have A Plan where people will be able to find a safe ride home. McConnville notes that impaired driving is completely preventable, all it takes is a little planning.
