Often when traveling by bus you're supposed to leave your big bag in the bottom of the bus. When there are stops before your final destination someone could just take your bag.
Of course I wouldn't leave valuables in this luggage, but it would still be extremely annoying if it got lost.
What is a good, practical way to avoid this luggage stress?
I'm looking for a way that also works in third world countries (i.e. no tags) and that doesn't require me to be very alert at intermediate stops before my destination (possibly at night). I have an ongoing travel insurance, which helps somewhat but it would still be a major hassle if I lost my stuff.
Would some kind of chain be a possibility? Some chain that can be quickly attached without annoying bus company personnel, is there something like that? Could it work?
