The FTF for this cache gets the title of the cache changed to refer to them as their FTF prize ;-) There will also be a prize in the cache for oceanwaves22 - please leave it for her.
Both parties have claimed their respective prizes! :-)
The cache is not hidden in the play structure itself, but elsewhere in the park. Avoid searching for this cache during daylight hours. Be mindful of the nearby homes and watchful eyes from the windows if you are searching at night.
Please make sure you close the cache container well to prevent moisture - I'm curious to see how long a container of this sort will last.
