A 15 mile electric fence charger can put out quite the shock.
And when a wire is goofed up and touching a fence post, said fence posts become electrified as well.
And when you're leaning up against a fence post, not knowing that a sister just turned the fence on, you might find yourself the recipient of a "shocking experience".
Long story short, there's nothin' wrong with my fence. But boy howdy was I tingling from head to toe for an hour...
