The picture’s caption from CHS Flickr pool shutterbug coreygo is true — we can’t explain it. Here’s our open thread for 2010 Halloween on Capitol Hill goodness. We’ll add the little bits we find today and tonight. Please feel free to join in the fun and add your pictures or observations in comments. Check out the CHS Halloween guide for a trick-or-treat map and more. Have something you’d like to share? Send it to [email protected]

Another favorite pool contributor sea turtle has also been busy. He’s already posted some of the highlights from last night on Broadway. You can also check out our photos from the Procession of Lost Souls costume contest.
