I'd rather cure the meat then can it, but either will work.
I see a lot of planning short term here for right after the SHTF, but there is another scenario that you should plan for...
It is a lack of supplies in stores and a collapse of the economy. You don't just need food and perishable in barrels or buckets you must be able to grow your own and live without that freezer and electricity (unless your solar)
I see a lot not all of you living in a tent, out of you buckets and thats great one you need to be mobile but you need to work on long term survival skills also. what do you do once the economy has hit the fan. Good Luck if you have not been already living the old way, it takes years of trial and error to even grow a great garden consistently.
When I tell you I am a Mountain man, I mean I can trap, hunt grow my own food and store it long term, I can make my own clothes and shoes, I can live on my farm or if I had to leave I could live for years in the mountains, Look I am not bragging. Just letting you know that this is what you will need to be able to do also...
SURVIVAL IS NOT HAVING ENOUGH FOOD TO LAST A WHILE, SURVIVING IS HAVING THE SKILL TO LIVE IN THE WILDERNESS FOREVER.
