It gets windy here and folks are constantly dealing with layers of hats and scarves and gloves. You're bound to drop something at some point and have it blow away. But rather than getting trampled, oftentimes, somebody will pop your lost item on a fence tine in the hopes that you'll be back by that way to reclaim it.
Heck, once I even saw an entire outfit. It started with the tie.
Just the other day I became part of the process... I found a sweet little pink mitten that some little girl was bound to be missing. So I put it on a windowsill where she might find it.
