You guys are awesome! Jen, you are cracking me up. I love the way you are really thinking this thing through. You know, I could just send you some chocolate. All you have to do is ask. LOL You are going to laugh when you find out the answer.
Here are two more pictures, so keep guessing. We do have a winner but I won't tell you who yet or whether they left the answer on my blog or emailed me (I've gotten a couple of private emails). That way you need to use your own detective skills to figure it out and not just look at the answers others gave. :-D
Here's your hint based off of your comments. It is old! How's that for a hint. ;-)
