#879 guess the photo

I didn't have anything specific to write about tonight, so I asked T to pick a year between 2006 and 2012. He picked 2012. Then I asked him to pick a month. He picked September. Then I went to my files and picked a photo I took in September of last year to share with you.

Can you guess what this is?

Take a guess, and I'll tell you the answer tomorrow :)
