As someone who is physically attached to her camera, I can't imagine what I'd do if I ever lost it or my memory cards.
This blog provides a place to post pictures from found cameras and memory cards in hopes of reuniting them with their owners.
There's a recent post of a camera found here on the East Side of Milwaukee, so I'm cross posting it in hopes of finding the owner.
Fujifilm camera found, Milwaukee
"I found a pink Fujifilm Fine Pix camera on the east side of Milwaukee, WI., near UW-Milwaukee campus the morning of January 4th. The camera was found demolished and damaged beyond repair, but I salvaged the 4 GB memory card. I am more than happy to return the card to the owner, but I have tossed the camera as it was so badly destroyed."
