Just been reading Food for free by Mabey. Got the hardback for £10 and the little collins gem version for just under £4. Bargain. Amazon special deal BTW. Looks a very good book/s and I hope I will get to go out and see what I can see with the little book after reading the big one at home. I only got it after spotting it in the bargsains section and having heard it was gd on here.
