Re: Bee-ware Bear!
Looks well designed and should give all the animals pause.
Something we learned when electrifying a garden plot: If you have small critters getting by, grounding the lowest wire is an effective action because it makes quite a good circuit when touching the first and second (read hot) wires simultaneously. You could expand that idea by grounding every other wire going up the post -making it a lot easier to get a circuit to ground where the bear operates. How long is your grounding rod? HTH
