Some people have workshops in their backyards or garages.  One of our neighbors has a workshop in their garage.  I don’t know if he has hydraulic power workholding or what types of machines he has, but I do know he works in it a lot and sometimes his son is out there with him.  I have no idea what he makes in his workshop but he does seem to enjoy being out there.  Maybe just puttering around in the garage is therapeutic for him and he doesn’t always have to be making something.
