Tom Vonhof, Lakeville's police chief, has visited some creative neighborhoods during Night to Unite.
Last year, two adjacent houses opened the gates to their back-yard pools and threw a massive pool party. The year before, a race car driver showed off his car in a church parking lot where a rock band played and clowns entertained the kids.
Occasionally, he said, helicopters land at parties. He's even been to bashes that go to the trouble to get sponsors.
"We never know what's going to be at each individual party until we come up," Vonhof said. "Every neighborhood interprets it differently."
Tuesday is the night, and whether your community calls it National Night Out or Night to Unite -- same concept, different name -- you probably know the drill: Lock your front door, turn on your porch light and join your neighbors outside.
Minneapolis embraces the event wholeheartedly and consistently wins top awards for cities of its size, but participation in Dakota County communities has grown, too.
In Eagan, "We had 20 neighborhoods in 1998," said Crime Prevention Specialist Jill Ondrey. "In 2005, we had 60. Last year, we had 192. It seems every year the community gets more excited and more involved. It just has become part of the fabric of Eagan."
"It's amazing how it's evolved over time," Vonhof said. Twenty years ago, during the first event, Lakeville held 15 to 20 parties. This year, 75 have registered so far.
