I wonder if anybody has any suggestions as to how I can secure our garden gate. we need to go shopping on Saturday afternoon and we need to secure our metal garden gate to stop my fil from going out onto the road the front garden is big enough to be away from the house if he wants fresh air or gets it into his head he wants to go see his friends (he doesn't know where they live) the house is all safe and he cant turn anything harmful on but we have got the worry that he might have a thought he doesn't do it all the time but we need to make sure.
