I was at the park doing some drunken ghost hunting with my husband, and finally caught a picture of something.

It's in a cement train/fountain thing, and in the original photo, it looks like a little boy with his knees up against his chin. On Piccassa you can see a little better, but not clearer, so it just looks like... something.

I have before and after photos within seconds of each other so that you can see that something actually was there and then disappeared. Obviously this isn't total total evidence for the existence of ghosts, but it's still pretty cool.
