Having food in the pantry, is always a good idea. Some wanna have weeks , months or years worth stocked up.
If you have med's stored, thats good to. Fuel, water, and tools or other gear is also a good idea.
The biggest problem with some people, will be leaving your supplies, if you have to bug out.
If you don't have a way to transport your supplies, your going to have to eat or use what you can't take before you go, otherwise...you will be
leaving it for whoever finds it. Thats not a bad thing, but ..its waisted money.
Do you have a place to go? Is it a shelter or out in the woods to live off the land?
To take the water needed for an extended stay, would be a lot of weight and space.
In many cases, I think it would be better to have some water, but ways to aquire more along the way, and ways to collect it and store it once you get
to where your going.
If your on foot and walking to a BOL, you might be a couple of days from it...with hiking to it and carring a pack, you will be more than likely,
taking a road less traveled...so to speak. So, you will probably need or want a lot more water, as you will be needing it to keep moving quickly.
If something happens to your vehicle and you cannot get it and your stuff to the location..can you make it without it?
I highly suggest that if you store or stock things...that you don't keep all your eggs in one basket..so to speak.
