Not to be critical but in todays age 2 words that don't go well together are "urban" and "survival". The best supply you can have in an urban survival situation is a good supply of rural areas where you can get out of urban areas.

Regardless of the situation urban areas will just be plain bad at best. If we experience any disruption in our supply lines whether it be from invasion, economic collapse, civil unrest etc it will take about a week for stores to be completely out of food and supplies. Once this happens you will have to contend with the masses that were unprepared and looting, murder and pillaging will commence and regardless of the supplies you have acquired you will eventually be defenseless.

If you can make it to a rural area you will stand a much better chance of survival for yourself and your loved ones. In a rural area you will most likely have a good supply of wildlife to survive on. If you plan right you can also have plenty of fresh water and you will have a much better chance of avoiding the mass gangs of desperate looters that will be left in the urban areas. Any urban area during a time of war or collapse will be about as close to he'll on earth as you will ever want to encounter.

I recently moved from Central Florida where the county I lived in had a population of 300k+ to North Dakota which has a total state population of around 500k because I am expecting things to get pretty bad in the very near future and I did not want to be stuck in a place where I had to risk fighting amongst others to survive. Survival is hard enough sometimes without having to worry about constantly defending yourself.

Im not saying you should pack up family and move.to another state but you should definitely have a plan for yourself and family and get as far out of town as possible. Thia plan should include a predetermined rally/ reandaveuz point for everyone to meet up at.

ETA: One thing I would suggest for anyone prepping for survival would be The SAS Survival Guide. It can be bought on Amazon for about $15a and is a very comprehensive guide and learning tool. I went through SERE training and the SAS Guide is as close as I've seen to actual military publications.

I hear you CSBowie...all my eggs in 1 basket..no
everything I do, have done..do I post here...no
I post as reply's to people or to get people to think...WE(you and I) seem to have a lot of things in common..ideas and thoughts.
I don't post them all here..It would take a book to put all the info out there...and quite frankly, there are hundreds of books alredy out there with some good info.
It appears that like me, you have lived in, seen. been to..areas that were in a SHTF...so you have a way better view on it..than most. A lot of the people think its like a video game or a movie..and they will have instant skills.
They also think they can throw the back pack on..then run and gun day and night...so there is a dream world out there..that a lot are thinking is real...thats why I started this tread..like I said in earlier posts....I wanna get people to think, to use there head for something besides a hat rack.

See I have this crazy idea...let them do some research and ask questions...no questions, then they are good. I will gladly help or assist if they want it or need it..but they have to ask.
That way I don't give up all the little secrets that I might or might not have...if I tell all, then you might actually hurt yourself in a SHTF...because the guy down the street read your post, and did it before you..so he got the items or things..just my .02 cents on it

I have a simple bug out bag build. Made one for my wife and for me.

I have a simple kit for an on the run approach. Take the essentials only. Light load. With just my wife and I, I only need enough food and water to last for about 3 days. In my experience, 3 days is enough time to find a spot to recharge on supplies. However, it's best to know where that spot is and about how long on foot it will take to get there. The supplies carried would be focused more on food and water.

9 field stripped MREs. Packed right, these wont take up that much room. Might even add a few power bars or protein bars.
Two canteens of water. Coupled with purification tablets, these are easily refillable. Also if you can get the military issue canteens with the canteen cup, that canteen cup can be used to boil water. A camel-bak is also a very useful thing to have for hydration. I would recommend getting one.
6 pairs of socks and underwear. And 3 extra shirts. And maybe another pair of pants, preferably jeans. Also a polar fleece jacket would be nice as well as gloves and knit cap. And if you feel necessary, another pair of shoes besides the hiking boots you should be wearing. And if you have room, you could try and fit a Gortex style rain coat. But a simple plastic poncho will work best for saving space.
You'll want a heavy blanket, preferably made of heavy duty wool. You'll also want a space blanket still in its packaging. Also a light foam mat that can be attached to the outside of your pack is nice to have too. It's not heavy and it's usually pretty easy to attach.
A good tarp is also something you will want. It's a lot easier to carry a 10X10 tarp than a two man tent. If you also carry about 100ft of 550 chord, you'll have the means to set up a pretty solid shelter.
Then comes the little things. You may want to have a headlamp as well as extra batteries. You will definitely want a waterproofed fire kit. A small plastic container that has matches, magnesium block, and even flint. Having a spool of fishing wire and hooks can be helpful for fishing and snare lines. A pocket knife is also a must have. And if you feel it necessary, you can also carry a pistol and a few magazines of extra rounds. I don't have a pistol, yet, so that's not a part of mine. Also a solid first-aid kit is a necessity. You'll want to include band-aids, gauze, medical tape, sterilizing material, and even thread and needle. The thread and needle can be useful for stitching up wounds and even patching clothes.
As far as what kind of pack to use, look in to BlackHawk gear. I would recommend the Tactical RUSH 12 or 72 backpacks. They're big and they have ways to attach stuff on the outside.

That's it. You can add anything else you think is necessary, but this is usually what I would take when I've done my yearly "survival excursion" with the men in my family.

Echo3Foxtrot..sounds like you might have an Idea about what your doing...and how to get it done. The biggest thing would be having a safer place to go..if you've got that..then your good to go!! semper fi.
