The challenge here is not getting to GZ. That's the easy part.
Overlooking the playground at Mundy Pond it stands very prominate but somewhat lonely. A great place in the summer to sit in the shade or if the time of day is right, lie in the sun.
The area plays host to a softball field, skate park, soccer field and playground, so it can be a very busy place depending on the season so stealth will certainly be your top concern. There isn't anywhere to hide you while you conduct your search.
At the time of placement the cache was tucked away hidden from sight, so please help to keep it that way so that it doesn't get discovered by muggles. It contains a logsheet only so be sure to bring your own writing utensil.
