I practice what I’ll label the BIT method of travel: Buy It There. If you pack for every possible contingency—better bring the hiking boots in case we go hiking, better bring an umbrella in case it rains, better bring dress shoes and slacks in case we go to a nice restaurant, etc.—carrying a mule-worthy load is inevitable. I’ve learned to instead allocate $50–200 per trip to a “settling fund,” which I use to buy needed items once they’re 100% needed. This includes cumbersome and hassle items like umbrellas and bottles of sunscreen that love to explode. Also, never buy if you can borrow. If you’re going on a bird-watching trip in Costa Rica, you don’t need to bring binoculars—someone else will have them.
