Slightly off-topic --- but maybe a bit encouraging ---
On our first-ever trip to Europe about 17 years ago, we (actually my husband) left our camera on the train (the German Rail). About 15 seconds after we stepped off of the train, we realized we didn't have the camera -- but the train was gone. This was on a Sunday afternoon, and we were travelling to small towns -- no stores open to purchase much of anything, much less a camera. We were going to see Neuschwanstein -- the "Sleeping Beauty" castle. Well, we just had to be content with just purchasing some postcards from the gift shop. We went ahead and bought a new camera the next day when we were in a town large enough to have a store.
When we returned home to the USA, I was very pessimistic, but my husband decided to write a letter to the German Rail corporate office. Fortunately, my husband had recorded all of the pertinent information about the camera, including the serial number. We waited quite a while --- It was probably a month later when we heard from the German Rail. They had our camera! They told us how much money to send for shipping it to us, so we did.
When we got the camera, we had the pictures developed (35mm camera -- before everyone had gone digital). Not only did we have pictures that we had taken --- but we also had some very nice pictures of the train attendants from the day that we left the camera. They took pictures of each other before turning the camera in to their Lost and Found. Even though we didn't take pics of the castle, those pics of the attendants are a great memory from that trip.
We were lucky to get our camera back. Chances were probably NOT in our favor.
Since that trip:
(1) We are always sure to record serial numbers for everything that we purchase.
(2) We are always sure to label contact information on everything that we purchase --- cameras, ipods, cell phones, etc.
