This cache is located in yet another park you probably didn't know about. Of particular interest in this park is the Frisbee Golf Course set in the woods. The cache is located nearby the course so bring your discs and play a round. Make an outing of it and sign your name and score in the log.
You are looking for a looking for a 12-inch long PVC tube. It's in plain sight. To access the log sheet, simply pull the pin from the bottom of the tube. There is no need to untie it from where it hangs. The dowel attached to the log sheet will help you spin it into a tight roll. Reinsert the log in the same orientation as you found it and replace the pin. There is no room for swag. Bring your own pen.
Note, I've never been here and not seen folks playing the course so please be careful of the muggles.
