'Tis mystery all...

I like Admonit's idea of posting mystery photos here and leaving you all in suspense for a while. So, without further ado, here's one. Please post your guesses in the comments. Maybe this will lure a few of you lurkers out of hiding. I'll report the answer in a few days and will keep score of who gets it right. Hint: this one was taken on November 25.

To post a comment:
1. Click on the "COMMENTS" link below a post.
2. Type in your comment
3. Choose an identity. If you don't have a Blogger account, you can still leave a comment, either as your name or a pseudonym if you prefer -- preferably one that would let me guess who you are but you'd remain in cognito to the wider Internet world. For either of these options, choose "Other" and fill in your name or pseudonym (you can leave your web page blank if you don't have one). I'd rather you not post under the third option, Anonymous, but there's no way in Blogger to disable that option without also disabling people from posting who do not have Blogger accounts. If you do use Anonymous, you can always still sign your post if you like.
4. In the Word Verification box, type in the funny squiggly letters you see in the picture above it. This is to verify that you are a human being, to prevent automated spam from showing up here.
5. If you want to check out how your comment is going to look (good idea if you use any HTML code in it), click Preview and make sure everything comes out OK. Otherwise skip to step 6.
6. Click "Login and Publish" (or if you did Preview first, you can also click "publish this comment")
