Red Light, Green Light

RAY: The hint I gave was if I had used this puzzler a few months from now, the flaw might be much more obvious. Now do you know the answer?

TOM: Ohh, a few months from now I'm going to guess that would have brought us to winter.

RAY: Yes.

TOM: And in some parts of the country it gets cold and snowy.

RAY: And because these lights use so little energy they emit no heat.

TOM: Yeah.

RAY: And when wind blows snow and sleet and whatnot --

TOM: It stays right there. It doesn't melt it.

RAY: Exactly. And the old incandescent lights used to melt the snow. In fact, I talked to the chief traffic guru in Our Fair City of Cambridge, Jeff Parenti, and he said, oh yeah, this is a problem that nobody foresaw.

TOM: Of course. That's why we shouldn't live around here. Just another reason.

RAY: So who's our winner?

TOM: The winner this week is Alma Blum, from Palmer, Alaska.

RAY: Oh, Alma, Alma you're going to need a prize.

TOM: And for having her answer selected at random from among all the correct answers that we got, Alma is going to get a 26-dollar gift certificate to the Shameless Commerce Division at cartalk.com, with which she can get our new CD collection called, Four Perfectly Good Hours. Congratulations Alma for being this week's puzzler winner.
