Box of nails have not moved

This was my test - a new box of nails ($2.98) left out on the porch.

Took a photograph of them on Friday to note position, and today they are still there - haven't moved.

I'm sure someone has nicked my other roof nails, so this was a test to see what would happen.

Either that or I left them on the bumper of Dog and drove off on Wednesday.....(which i'm sure didn't happen).
