Stephen Barrows from Plano emailed me the other day with a great question. Here it is:

I've got a question you probably can answer. I live in Plano, but I see this in other cities, too. On the ends of the arms of traffic signals there are signs, or something, facing upwards, so only people in the air can see them. Street names seem most likely, but these things are only about one fourth the size of the signs we on the street see, and we're a lot closer than you folks in the sky, so I wonder. Do you know what I'm talking about? What are they? What's on them?

I could only come up with one answer and that would be....solar panels! Plano is a leader when it comes to proactive energy saving in the area so it makes sense to me. I'm going to fly up there this afternoon to confirm my hypothesis. Thanks for a great question Stephen!
