I just started to read this little web, and just about had a hart attack. The three things about this life style, are safe, sane, and consentual, well some of you have forgotten the first two. Before you ever think about attaching anything to a wall, or cieling don't. The structure of you home beit an apartment ot house can't handle somthing atached to one or two points and be able to suport the weight of a person 97lbs or more. If you do all you are doing is slowly bringing down the house, and you won't know it till it comes down on your head. Know there is a way of doing it but not from what I have seen in this thred, and to do it would be vary open to anyone that sees it. Know you can fix something up that can do it but you have to do to you celing, and or wall what is done to the floor so suport the wate of you , and everything in your house, and hooking to one, two, or even three beams, or rafters is not going to do it, remember thay already are suporting the building in the first place. So before you bring down your homes please ask someone how to strinkthen your wals, and or ceilings first.
