I have driven through this park several times looking for the right GZ. Today, I finally saw the light! This is unlike any of my other hides! On game days this hide can be muggle infested. Fortunately, I tucked it away for you. However, please use stealth to preserve the hide for others.
Look for the concrete path that leads to the park.
