Extreme heat may prevent more than a few National Night Out events from taking place this evening. Still, thousands of Minnesotans are expected to fill the streets for the eighteen-year-old event which aims to fight crime by encouraging neighbors to get to know each other. Brooklyn Park is going for its tenth national record in a row for the number of block parties for its under one hundred thousand population. Lee Glamm an officer with the Brooklyn Park Police Department says he registered 164 parties, although a few were cancelled due to the heat and many others have decided to move their gatherings indoors.
