You cannot survive without sufficient clean drinking water, sufficient food, followed by sufficient shelter and a sufficient means of self defense. These four things are absolutely, positively essential to your survival when disaster strikes. Without these basic essentials you will not survive; so it is worth repeating……. You must have sufficient clean drinking water, sufficient food, followed by sufficient shelter and a sufficient means of self defense. Start preparing today!

Have you checked out the Sawyer water filter? One of my buddies just got one, so far it looks like an excellent filter.

I will check it out CDP. Right now I use water purification tablets and a straw connected to a filter for emergency use.
I stumbled across a site the other day, that I thought you might be interested in sharing. It is a free, printable survival guide, covering topics from bush-medicine to child birth, and traps/snares to building shelter and water filtering devices. It is a pretty handy guide, and I printed a couple copies for my car and basement. http://www.doomguide.com – It sounds kinda corny, but the information is handy and concise.
I appreciate the information. Thanks for sharing Lord Brockington.
Collecting and storing rainwater is a good source, but in urban and built up areas, drinking rain water without filtering first is suicide.
Agreed. Making sure drinking water is clean is absolutely essential.
You missed something off the essentials list….TEA!!! A true Brit cannot survive without TEA!! It is vital to every working organ in the Brit body 😉 We cannot survive many ardorous trials and challenges but no TEA?? That is the point when we know we are truly in a SHTF situation!!
Speaking of tea, we have a new store that opened in my area called Teavana. They basically sell loose tea leaves that you buy by the ounce and they put it in a tin and you then brew it at home. My son is really into the whole tea thing; drinks a cup every day 🙂
