The cache is a camoed container bigger than a spice bottle but not as big as a normal ammo box. Although this park is often empty, it is also quite small. I do not advise trying to search if muggles are present. Original contents of the cache were:
soccer carabiner with key rings
“Honeymoon Bug” TB
Sacagawea dollar coin
logbook with pen
This park has some lush ivy. I hate ivy. The cache is not in the ivy.
