This area of Fairwood is home to a small trail that connects to a wetland and a playground. Parking is easily available at the trailhead and it is only about a 1 - 2 minute walk to the coordinates. The exact spot is slightly off the trail and the trail itself is rarely busy so it should be pretty well protected from muggles.
Please note, there are signs on the trail that says the park is for community residents and their guests. We have never noticed a problem with anyone being stopped for being in this park, but if someone does stop you it is okay to mention that you are a guest of the Rich family on 176th St.
