Ok, so I are thinking of pre-empting the thieving cunts and putting in a ground anchor of some description. Now I have got a fair bit of space to pay with and can have something of real FOAD dimensions to act as a deterrent and thought that something of the ride-in variety along the lines of the ones you use to park push bikes in might do the job nicely. Are such things available retail or do I have to offer beer tokens to someone with a scaffold pole and a welding set to make one?
