The oak tree
Once she arrived at the location, Cindy double checked the coordinates once more. This was the spot. She didn’t see anything strange around her. Green grass, acorns here and there, a forgotten pile of dog poop… typical things you find in the park.
Underneath a large oak tree, Cindy puts the shovel in the grass. Despite her age, she was still quite fit, so a bit of physical labor wasn’t going to deter her. Thankfully there was no one else in the park… she would have surely gotten some weird looks.
At around half a meter down, Cindy runs into something hard.
