OK this one's not so eazy. You'll have your plate full looking for this one, particularly as this is one of the most muggliest areas in town. You will need to plan your arrival time at the GZ very carefully so you don't have a wasted trip - as this is a very busy area. I would suggest 6am to 8am would be the optimal time.
No geocaching licence is required.
This is a very picturesque area - be sure to take some photos of the surrounding area when logging!
