This park is a favourite for many different species of birds. It is also frequented by a multitude of muggles, their canines and offspring. It has a small playground, a picnic table, basketball court, and even a dog bowl and tap.
The first cache is a small container, large enough to hold trackables. It should be fairly easy to find, but don't get used to it - the others are much more difficult. In this cache, you'll find the coordinates for the next piece of the puzzle. It's up you you to figure out what they mean. If you're still struggling, send me a message. I'll help out without spelling it out.
Please be gentle with the caches, and replace them where found (unless that looks obviously wrong). Any maintenence at all, just send me a message and I'll go sort it.
Congratulations to Lachlan1.77 for FTF, and in the dark no less!
