High-beams

I just returned to campus from a weekend with my folks in Boston and I've a splitting headache: some nut-case on the Taconic was not only driving like an idiot (speeding up and slowing down at random, driving parallel to cars in the slow lane instead of passing them, &c.) but was doing so with his high-beams on. I did manage to get behind the fool, but he'd been behind me for some time and his headlamps had already done their damage. Qué será, será, but still, what a pain.
