For the sake of potentially sounding crazy.........

Bought an older house. The previous owner (who I never met/talked to)
stuck one-foot sections of rebar (like they use to reinforce concrete)
into the soil around the garden. The rebar is "planted" vertically
(with about six inches protruding from the soil) and is spaced about
six feet apart and is connected together with thin , bare wire.

Anyone have a clue as to what the purpose of this is??????

My uneducated guesses are.....

- adds iron to the soil? (does not explain why connected with thin
wire)
- keeps varmints away? (how?)
- some kind of electrolysis action going on?

Any wacky replies are welcome.
