WTFC-
Right or left, it doesn't matter! An ambidextrous sky hook will also work.

Or, you could use a local ACORN or Obama supporter to hold it!!
I did it outside from a shooting bench so 30-50 yards wasn't a problem. For the bob, I used a piece of 5/16" or 3/8" rod and put a 90 deg. bend in it about 8" long. Jam it in the ground and hang the bob from the 8" leg.
A sawhorse, tripod, etc. will also work. Needs to be done on a calm day otherwise the bob will be bobbing too much.
