Why not???? Even a small charger will run a line of 2 miles or so. That should be enough to go round the vineyard a couple of times at least and they're not too expensive. That's what I've decided to do for next year on my garden. For the first time, the deer and racoons have decimated it. The squirrels got every plum, peach, pear and apple on the trees. There are still some pecans but it's just a matter of time before they clear those out too. If I'd been a true redneck, I could have filled the freezer with deer meat. I did get a couple of racoons but it seemed as if some more moved in almost immediately so it's back to square one. If you throw in the armadillo that tearing up the yard, no I haven't caught it yet either, this has been the worst year ever for wildlife destroying stuff. Next year ... electric fence and let them FRY.
By the way, that's still a great looking project!!!!!!
