Hi Dukat
I do have a head for the hills approach to any sudden crisis, like food shortage. By the time any SHTF the wife and I will temporarily go camping
With a bag of Rice and some salami (Yum).
Just to escape the hoards when they are panicking, we will then return.
There is nothing wrong with trying to protect ourselves IMO. And survivalism (aka bushcraft in many ways) is really good for the soul.
I got an allotment as well and have met some really good people through it.
I think you'll do ok, 'cause you seem to be honest with yourself.
