That is some really nice work there. I think it will keep the bears at bay. My only criticism is I would not have alternated charged and ground wires... I would have charged all the wires. I did notice that you are on some pretty sand soil though, if that dries out the fence will probably stop working due to an incomplete circuit. Which I guess is likely the reason you alternated wires.

I would not bait the fence. The bees will be plenty of lure to attract the bears, no point in adding something extra.
