I'm sorry, but have we really had a rash of kids picking up nuts OFF THE GROUND under squirrel feeders and eating them? Not that I've heard of!
I think this is a case of complete paranoia about protecting someone with nut allergies. Don't get me wrong - I know it's a potentially deadly affliction, but I think this is going just a bit too far!

State to Squirrel Feeder: Nuts to You!

Ugh. <walking away mumbling>
