Welcome to Arden Street Oval.
This is the home to the North Melbourne Football Club and is often used as a hub for excersise and sports. On an average day you might see people walking their dogs, kicking the footy, or doing laps of the oval.
The cache is hidden in an area overlooking the oval. Muggles should not be too big of an issue, though there will be some people walking around the oval, as well as possibly a couple of people coming in from behind.
It holds a logbook, though not enough space for anything else. Remember to bring a pen or pencil.
Enjoy.
