Dunno mate.cant help wonderin why the gates been unlocked 3 times now.It definately cant come undone in the wind as its a bitch to open anyway.As for what you said Stu,I am away at 3 in the morning.Nice idea though Maybe theyre waitin for us to forget to put the extra patio locks on?God help em if i catch them though.I got a pick axe handle with a metal end on it under the stairs that we used to use when I was in the forces.I will use the bugger as well.
