The
cheap way is to go up on a boson chair. Not easy, and scary if you've not done it before. Easy way is to have a yard
lift one of their guys up with a chair or crane, etc. They all have a way of doing it. Not
cheap. It may be possible to run a
boat hook, coat hanger, or something else up on another
halyard to bring the
lost one down, but I've never had any luck with that.
