I see superb travel photos from folks here, something I hope to do in the next year or so. With these wonderful but expensive cameras and lenses, what are some of your strategies for protecting them - - On the airliner - checked, carry-on, or around the neck? - In the hotel - never leave it, take it with everywhere? (I suppose that's much of the point of the trip, heh!) - Walking around - keep it from a swipe and grab? I'm saving for a full-frame Leica and two lenses, which makes me wonder about the above ... Thanks!
