A survival cache is a container of some sort which contains essential survival supplies that you would hide in a secret location. What you store in them is entirely up to you but most people will store extra ammunition and guns, food, first aid kits, tarps, tools, and anything else they think will be of use during an emergency or shtf scenario. It should basically contain the same type of items that you would place in your main bug out bag. Some people who have a bug out location selected have gone out and hid several survival caches along a secret and random path. They stock these caches with essential supplies that will help them along the way to get to their destination.
It’s extremely important to have survival caches in place and why you should have one should be pretty obvious by now. Lets say a disaster of some sort has occurred and you are unable to get home where your main bug out bag is located. Instead, it might make more sense to go to your secret location and retrieve your cache of supplies. Another example could be that society has completely broken down and a group of vigilantes break into your home and demand you hand over your remaining emergency supplies. Instead of confronting them it would probably be easier and safer to just hand over what they want and chances are they will leave you alone.
By having a survival cache in place you are guaranteeing yourself that you will have a backup of essential supplies in the event that you use up your main stockpile, it has been stolen or in case you are not able to get to it safely. By having the mentality that a well stocked bug out bag is all you’ll need, please think about this again and consider your family’s well being in the event that a disaster does strike. Perhaps you will be spared and a disaster will never directly affect you in your lifetime, but simply coming to the conclusion that you have enough stuff prepared could prove to be a costly or even fatal mistake. When it comes to preparedness, you’re never finished.
