the precautions that we always try to take while walking back late at night, but must say i never walk alone at night, always with the OH.. is to walk with traffic coming towards you, never coming from behind, and always have a torch in our hands and if someone looks a bit dodgy we light the torch up and shine it around there faces so they are aware we can see them... as yet we have never had anything dodgy happen to us but have know people that things have happened to......
