Welcome to the Richard E. Maslowski Community Park, a recently developed park located at the west end of Bender Road, a few blocks west of Green Bay Road in Glendale. It is so new that the Satellite version of Google Maps does not show it as of the time this is written. Maslowski Community Park is a joint venture of the City of Glendale and the Nicolet School District.
The cache is NOT at the given coordinates. Those are for the main parking area. You will have to solve the simple puzzle below to obtain the coordinates for where in the park the cache is hidden.
The Park:
As explained in the Powerpoint proposal for the park available on the city website
The overall concept of this facility is to provide a multi-generational gathering point for Glendale families and beyond, offering a wide variety of activities to enhance civic involvement and community pride. Our vision includes offering summer long activities of music, community theater, a family play area that is fully handicapped accessible, a beer garden, recreational baseball, WIAA/NCAA sponsored events, and a new location for other civic gatherings using the community room.

The City’s vision is not yet fully actualized, although the multipurpose civic building is complete (along with the summer beer garden), as are the handicap accessible play area, outdoor stage and amphitheater, the Glendale Veteran’s Memorial, and ample parking on the West side of the park.
During the summer, Richard E. Maslowski Community Park not only features the beer garden I mentioned, but also hosts both the long-running Music in the Glen summer concert series and the Sundays in the Park musical concert series. Information on these FREE music series and other information on the Park is available on its website.
Park hours currently are 8:00 a.m. to 10:00 p.m.
