It’s National Night Out Day. It’s a day that enhances the relationship between neighbors and law enforcement, while establishing a true sense of community. It provides a great opportunity to bring neighbors and law enforcement together. On that note, the Altoona Police Department will be celebrating National Night Out. Today, on Heritage Plaza in downtown Altoona, there will be a dunk tank, vehicle displays, food vendors and live music. The event will run from 6-9 p.m, and all are invited to attend.
