We geocached today, as we generally do on weekends. I took a lot of pictures, but I admit I wasn't thinking specifically about taking something to use as today's APAD(ish) photo. So when I got home, I went through the pictures I'd taken, and... well, I ended up wringing my hands over whether a deer skeleton was too gruesome to use as the picture of the day. But it's the coolest thing I saw all day, so I'm doing it. I'll lj-cut it, if you don't want to see.
When I first noticed it, I assumed it was a plant that just sort of looked like a ribcage. Nope. It was quite fascinating, if a bit gross.
Here are a couple of runner-up pictures for the rest of you:
