Some rabbit wire sold here is coated which should solve some of the
corrosion problems but if they are laid side by side they probably would
require scraping of the coat and welding every five feet or so to
maintain radial field continuity, and then re-coating the welded joint.
Any difference by "floating" in the dirt is a calculation above my pay

Definitely agree that most situations must be evaluated on their own merits and circumstances. I am aware of Rob's call but just thought this might prompt him to relay some of his experiences.
