Thanks for all the information and tips everyone.  I appreciate it. 

I have seen trinkets in LBs and assumed that the placer added these in case a geocacher discovered the box and wanted to take a prize. Better to take the plastic bracelet than to take the stamp... I think this is a good idea just as insurance, if there is room in the box.

Well, my Ferns Too box had a plastic bracelet in it when I pulled it yesterday. I know *I* didn't put it there! There are a few caches in that park, so it might have been a geocacher who left it there.

Whoever it was, my son was thrilled with it, because it was green, and he's into some cartoon character that's green at the moment.
