I'm still a little worried about this 'Loo shed'. What colour is it? Does it conform to local bylaws i.e. size and distance from dwellings, adjacency to underground water courses. As this is a mining area, do we know for certain that there is no subsidence in the immediate area? I would hate to think of the shed and several tents/caravans/vardas/teepees disappearing down a large hole and ending up being carried down a comunal water....No, it's too horrible to contemplate. Will there be a supply of gas masks?
