Thanks all, just been out again, been to virtually every house in the village now, walked round the nearest fields and am completely at a loss. It is so out of character for him, he is totally a 100% homely boy, he literally wanders down the garden, does his business and comes back in. I have personally checked most of the neighbours gardens and have called and listened in all of them. I have no idea what to do now, we are about to start making up posters and leaflets. I can't stop crying.
