I have a modest amount of prepping supplies -- food, ammo, batteries, etc. -- but the other day I realized something. I was planning what to add next, and thinking of things like solar powered radios and generators, when I realized something. While thinking about the exotic, I forgot the basics -- in this case, something as simple as nails. I didn't have many. Or screws. Or duct tape. So now, whenever I go to the local hardware or fixit store, I stick in an extra box of nails, or roll of tape, or cable ties, or something we tend to take for granted, but would sorely miss if we couldn't run down to the store to get more. Any more examples y'all can think of?
