All good basic info! Here's some more for folks interested in prepping.

It's important to also learn how to use the stuff. Simply owning tools doesn't make one proficient with them.

Magnesium fire starters are easy enough to use but they're not all made equally. Please practice with it and make sure you're ready to use it when the time comes.

The same goes for fire arms. You don't need to be a tacticool Rambo but you need to get used to handling and shooting weapons. Bigger isn't necessarily better either. In a SHTF situation if I had to choose between a .45 pistol or a .22 rifle I'd probably take the .22 because I know I can easily take down small game all day long and carry much much more ammo with me.

Seeds are very very important. If at all possible begin gardening now. Learn what grows well in your area, learn what produces well and is worth your time and effort. Learn when to plant and get a feel for how long it'll take to produce and how much water it needs. Potatoes are easy, calorie dense, and pretty stealthy. Growing food is a long term strategy and depending where you are it's likely to get raided and/or draw attention to you. Watermelons are delicious but squash is far more prolific. Green beans grow well for most. Lettuces can be good and grow fast but they're susceptible to bugs and heat/drought. Tomatoes can do well, cherry varieties usually will produce the most weight. Corn is great in some areas but where I'm at it makes no sense at all, which is too bad because I love corn.

If you get a radio then learn to use it! Get your stations pre-programmed, learn how to hit a repeater, keep your batteries charged up. If on the day you need it you've never taken it out of the box and the batteries are all dead then it's pretty much useless.

You may also want to consider buying some small denomination silver as both a hedge against the inflating dollar, but also for trade currency.
