Hello I am new to the forum and hope that someone can advise on ways to help my 86 year old father continue to live at home. He recently had his driving license revoked and has started walking. he will walk for miles not realising he has to get home. I live 4 hours away so it is very worrying, he has got lost and fortunately some kind person has taken him home. does anyone know of a suitable tracking devise or some other way of helping him get home. he does not have a mobile phone. Thank you for any help or advice.
