Ask any man and he will tell you size matters, but not in the case of reference books. Collins gem do a book for £4.99 in pocket size called "Food for free"
A great little book full of year round food to be gleaned from the hedgerows and fields. Even if you live in a city dont be put off, just as much food for free for you
10/10 for the prepper with an open mind.
Please bare with me in my ramblings, I'm an ageing hippy struggling to control the voices in my head.
