Cache you can find while going on a short walk by the lake and it's a great place to bring your pets. Great place to grab something to eat, take a seat and enjoy the view of the city. Sometimes lots of muggles, big surprise by the cache!
Short hike to the cache it's in a small gray container hidden near the shore. Cache contians a log, too small for a pen (please bring your own) there is also some loot to trade :)
