This playground was opened about eight years ago, much to my delight- I had a four year old and a baby at the time, so finding somewhere with swings and open space and lots of trees for hide and seek was wonderful! I've played so many hiding games among the trees in this little playground, it seemed only fitting that I should hide a cache here too.
You're looking for a canister, with some swappables inside. Stealth is needed; there are lots of young families who use this area!
Congrats to Mister Doctor for the FTF!
