sorry if this is the wrong place but I cannot find a equipment section to post in.

Does anyone have some tips or a link to information about the best place to put / use a kick bag. I was planning to put a hook/armature on the wall in my garage but then thought whether there are any know placement issues? How high should they go? Distance from wall, as you can get 2ft some are 3ft? weight restrictions?

any tips gained the hard way gratefully accepted!
