Does anyone know where I can obtain some sort of ID card or something that could possibly be attached to a keyring. My husband walks for hours and hours every day, he is still finding his way home OK, but I know it will only be a matter of time before he becomes lost. I have had to have the Police out a few times when he has failed to come home at a reasonable hour and as he doesn't carry a mobile phone or a wallet he has no ID on him at all in case something should happen. It was suggested to me that I made up some address labels and get them laminated but I know that Colin will probably lose them or throw them away as rubbish, so I thought maybe something that could be attached to a key would be useful, until he loses that as well!
