If you’re the rough and ready type, heading for the outdoors, then you’re probably only taking the minimum to begin with, or just what can fit into your expedition pack. Perhaps your destination is another city with all the amenities of home. Whatever the case, prepare a small backpack (some call it a daypack) that is separate from your main, larger backpack, or suitcase, and don’t check it in at customs. Consider this the ‘never leave my person’ pack that stays with you at all times, under all circumstances. I use two small metal carabineers to hook the zippers together on my daypack, which act as an excellent thief deterrent. Inside, keep that which you cannot do without, in case your main pack or suitcase is lost at the airport or lifted from your hostel or hotel. These include your passport, driver’s license, credit cards (and customer service numbers to cancel cards in case they’re stolen), cash, phrasebook, map, keys, paper and pen, and whatever else will help you out of a jam. If in the wilderness, the essentials may extend to other vitals such as potable water, rehydration powder and a first aid kit. In some situations, even my small backpack was not small enough to pass by the security guards in some museums and grocery stores (or they just thought me very suspicious looking). I’ve resorted to a smaller, two-zipper belt-pack that I can wear around the waist or sling diagonally over my shoulder. Slide it over to your front side when sauntering through crowded markets.
