MEXICO. Sonora. Caborca. Wednesday, May 12, 2021. Next to the church in Altar, Sonora, shops offer a range of essentials for desert-crossers: camo clothes, backpacks, black water gallons, first aid kits, combs, mirrors, card decks, balaclavas, and of course, painkillers. However, these goods are of very poor quality, making the already challenging desert trek even tougher for those who have no choice but to buy them at the shops’ hugely inflated prices, with basic kits often going for $200.
