This cache is located along the north stretch of the Wildhorse gravel buffer path.
To access the path, there's a place you can pull off and park to the west (off of Pole Line), but if you'd rather have paved parking you'll want to park on one of the many streets with access points on the east side (the closest being Rockwell).
This cache is pretty close to being a small size, but, because of the fact that it really only has room for a log (or really small swag items), I'm going to call it a micro. Good luck!
Congrats to Budzdunwerkin for being First To Find!
