Key to mailbox in front cash drawer, with red tag?

Not a huge deal, but when I go to the mailbox, I take the key in there, which had a little round, red tag on it. I can't find it now, I also looked in the drawer in Julie's desk, in case it got put there with the cash drawer and fell out, but I didn't see it. If anyone knows where it is...there's still one on the set of keys in Kathy's desk, that we use to lock up the cash drawer, and possibly other copies I don't know about it, but I'd like to find that one!

Jessica, if it doesn't turn up, I can go make another copy at some point, if you want.
