I need to start taking pictures to document this. I always thought that the park was fairly clean until Silas took to finding things.
The last time we were there, Silas found:
Half-eaten cheetos (they were half-eaten at the time of finding and we threw those out before they became fully eaten cheetos)
Pink and blue balloon shreds
One super moldy orange slice (Half hidden beneath a slide, I can only assume a thrifty child left it there for safekeeping)
A safety pin
A beer cap (budweiser. Yuck.)
Various candy wrappers (manufacturers, rest assured that you have designed packages so appealing that Silas can spot them even if they are 99% buried under leaves)
And my personal "favorite,"
A two-inch screw.
Everything else on my list makes sense. Those are things that people bring to parks. But a screw?
