We’ve established that to go light you just can’t take everything you might need. It will happen that you run out of something, ruin an item of clothing, or otherwise get caught unawares. This necessitates something that I really enjoy about travel - visiting local stores that everyday, local people use. A stroll through the aisles of a European grocery store is an eye-opening experience for an American; you’ll see and learn things there that you won’t in a tourist trap, gift shop, or high street boutique. You may just find that the local, everyday solutions are better than the ones you would have brought with you. And there’s also the wonderful possibility that your small crisis may afford a greater connection with the locals than the average, insulated, self-sufficient tourist could have. It’s amazing what a little dependence can produce.
