Jackson Playground is a small community space in the Potrero Hill neighbourhood. It's a surprisingly quiet spot given its central location, and it proffers a rare patch of green space in the otherwise quite industrial landscape between Potrero Avenue and 3rd Street.
The cache is tiny and well-camouflaged, but with a little luck and a keen eye, I'm sure you'll find this piper's pipes in no time 😉
Also, congratulations to purpIetiger and Ph4ded Tiger for the FTF!
