The cache is not at the posted coordinates! They take you to Victory Over Violence Park, one of several City of Milwaukee "Pocket Parks."
This is a bonus cache for completing the Civil Rights Milwaukee Adventure Lab. To obtain the coordinates for this Bonus Cache, you must first complete the related Adventure Lab.

Victory Over Violence Park
Victory Over Violence Park was created in the 1990s from a vacant lot that had become a magnet for violence and illicit activity. Its creation was championed by the late Jeannetta Simpson-Robinson, cofounder of Career Youth Development (CYD), which was formerly located in a building adjacent to the park. While the park had fallen into disrepair in recent years, the City and local Business Improvement District have been working the past two years to renovate it.
Victory Over Violence Park is intended as a beautiful, safe, and healthy green space to both remember those lost in Milwaukee violence in the past and serve as a place of healing for those currently suffering from trauma.
