This is always something I would think about in the back of my head during my first tour because I was traveling alone. I always took my most valuable items with me when I went to the showers or inside a store, but I realize that if someone truly wants to steal my stuff than there may not be a whole lot I can do in the end. I try not to buy top of the line gear precisely for this purpose, it would make the sting of losing it maybe a little more bearable. Still I'm confident that most of the time items I tour with should be secure enough.
