Costumes and candy -- that's what children think about on Halloween. But safety must be considered too, according to adults and dogs -- that is if the dog is McGruff the Crime Dog. McGruff and his Livingston Police Friends, Officers Gary Mankowitz and Joy Klapal -- as well as Chief Handschuch -- visited Harrison School to remind students in Kindergarten and 1st grade of the importance of being safe while having fun trick-or-treating. Judging from their smiling faces, the children certainly enjoyed the visit. Perhaps they will even want to dress up as McGruff for Halloween!
