The cache is not at posted coords. It will bring you to Horne Field. From hutchins st turn onto Sully St. Park by the tennis court. Another set of coords provided will bring you to the end of Wood St, another entrance to Horne Field. There is only enough room for a couple of vehicles on Wood St.. There is a baseball field and boat launch, swings, benches and a small picnic table with a roof over it. There is also a porta potty by the ball field if you need one.
Cache is a black magnetic bison on a bench. Should be a quick park and grab unless there are muggles near by.
