After reading in the Italy forum about a poor poster losing their camera, I just wanted to mention something I do now before travelling.
I'm sure we've seen the postings on Facebook where someone found a SD card with images and is posting the pics in hopes of getting them back to their owner. I write my name/address/phone/email on a piece of paper and take a photo of it on all the SD cards I will be carrying (I always clear and format my cards before going, so I make sure it is the first photo on the card). Then if I had the misfortune of losing one of the cards, or losing my camera (and hoping an honest person found it) then the contact info is right there on the SD card. Or perhaps photograph your itinerary in the hopes it could catch up with you (tho I would say that would be unlikely, but you never know!)
I found an SD card once in a parking lot and would have looked for the owner, but it only had a few photos of someone's dental work, so I assumed it came from a local dentist office, but had it been loaded with photos, having an address or email on the card would have been a great help.
And that reminds me right now to clear and format my cards and do the info photo before my trip to NYC in a week!
