There's a little hilltop nearby. I've lived in this neighborhood for 40 years and can't ever remember seeing Mow on it, although he lives right by it and goes everywhere around it.
This is a fairly simple mystery cache, which you solve in the field. The coordinates will take you to within 150 meters of the actual cache location. The photo is of the posted coordinates (where you'll be standing when you start searching) and was taken from beside the cache.
This is a microcache. It contains only a log book and pencil. Lots of muggles, so please be careful.
