Some people carry both, but most choose one or the other. Multi-tools are nice for everyday utility like opening a bottle or fixing a screw on your sunglasses. There are tons of great options from popular brands like Leatherman and Gerber. But as in most things, the 80-20 rule applies here, and you’ll find that you won’t use most of the features in the extra-gadgety options and should avoid the unnecessary weight.
Then focus on building up ammunition supplies. After a major collapse ammo will be more valuable than gold, and it’s generally not something you want to run short of. For the shotgun get a range of shells, from bird shot to rifled slug. In rifle and handgun calibers quantity is the most important factor; cheap military surplus beats premium ammo simply because you can buy more of it. The target effect difference between cheap and fancy ammo is incremental, but an extra round is an extra round.
The former Atlas E Missile Site, located 25 miles west of Topeka, has been redubbed the Subterra Castle—a turn-key property ready for post-apocalyptic inhabitants with four bedrooms and two bathrooms. The main residence boasts 5,500 square feet of below-ground living space, and another 3,500 square feet in a great room complete with a stage (you’ll have to amuse yourself somehow when civilization is gone). The facility was built in 1961 at a cost over $3 million, or $26.5 million in today’s dollars. It was purchased for only $48,000 in the early 1980s, and has since been renovated complete with solar panels, a diesel generator, and an 11,000-square- foot underground garage with a 47-ton drive-in door. Up on the surface, there’s a separate 750-square-foot house, and the 34-acre property comes with a stocked pond, a chicken coop, and orchards where walnuts, apples, and pears grow.
