That place mentioned on s Broadway in Englewood is called Farris Survival LLC at 3366 s Broadway--about 2-3 blocks N of Hampden.
I was in there a few years ago and most of what he had was food and water storage supplies. It was ok --But not great.
I stopped by about 6 months ago and it was stocked pretty good and his supply inventory was a lot better.
Berkey water filters--lots of books--medical supplies (even kwik clot)--food supplies were pretty good.
He has 50 and 25 lb bags of a variety of organic grains and a good supply of mylar bags and oxy absorbers.
A lot of water storage containers in various sizes and food grade buckets.
The food grade buckets are pricey ($15) but they are the good ones with screw on lids. I get mine free from King Soopers bakery dept.
If you live in the area --it's worth checking out.
