Ok, here is the situation. My 15 yr. old daughter is going to Mexico next Friday on a mission trip. They will be working out of a well established childrens home that is not near any of the major cities, tourist areas, ect. They will also be working with some of the outlying villages and such. I am pretty comfortable regarding her safety there I know the people she is going with. However, I would like for her to take a handful of items just in case of the "worst case scenario". She has never been interested much in "outdoors stuff", but if she were to get separated from her group, or a small group get lost, that kind of thing; I don't want her to be completely unprepared. They are flying into Chihuaha, so I'm not sure of items that may be restricted in her luggage. Obviously, the top three in importance are water, shelter, fire (not necessarly in that order). Would any of you like to offer some suggestions? Obviously, I realize that sending her with my .357 is out of the questions.... Thanks in advance for your help.
