Not everyone is like me and takes their camera everywhere they go, but this is the time of year when people will be taking their cameras a lot more often. I recently found a camera in the shoe department at Bass Pro. Yes, of course I turned it into customer service, however, I would have preferred to have been able to contact the owner myself. That way I would have known that the person would have gotten their camera back, because I would have returned it myself, or told customer service that the owner knows where to come get it. In this incident, I'm trusting that customer service department has honest personnel.
What you need to do is to type up in a large font, your name, email address, and phone number in your word processor or graphics program. If you don't have one, you can even write this information on a big piece of paper. Next, take a photo of this information. Never delete this photo! If you do, just repeat the steps above.
Now, in order for this tip to work, a very honest person must find your camera. I like to think that there are more honest people than not, so hopefully, if you leave your camera behind on a bus or at a restaurant, you will have a better chance of getting your camera back.
Have a fun Summer and take LOTS of pictures!
