Are we human...directionals?

One of my current favorite songs to spin to is "Human" by The Killers. Other than the fun mellow techno vibe of the music, there are a few reasons I like it. Well, The Killers are from Las Vegas, so that's cool. And, I'm convinced, the lyrics are about sign twirling!
This is the chorus:
Are we human, or are we dancer?
My sign is vital
My hands are cold
And I'm on knees, looking for the answer
Are we human, or are we dancer?
Obviously your sign is vital if you're a human directional. And yes, in chilly weather your hands will get cold. Gloves can make it difficult to hold on to the sign, unless you get some of those Madonna fingerless gloves (but lace is hardly warming anyway!).
The song ponders the classic human conundrum "What is our purpose?" in terms of sign twirlers. On one hand we are Human Directionals, that is, we are to point the way as a sign, that were it not human, would be prohibited from the public walkway. On the other, we are entertainers. We are sign dancers trying to attract attention. Sign twirlers constantly struggle to find a middle ground between these clashing ideologies.
The Killers' new song is a musical exploration of this struggle!
However, according to their website, the lyrics were supposedly inspired by a disparaging comment made by Hunter S. Thompson about how America was raising a generation of dancers. Obviously, though, there is more to it.

Watching the Friendly Skies

A few weeks ago, nearby Nellis Air Force Base had an air show. I was working while the Thunderbirds did their demonstration through the air. But I got to see them flying around a little bit from my corner. It was pretty cool. Since then I've been paying more attention to the skies while I'm at work. Being in the very North of the Las Vegas valley, and only 6 miles from Nellis, any planes above me most likely come from the AFB. The Las Vegas airport is way to the South and I think the commercial flight paths are not allowed over the Northern valley (thanks fancy homeowners!). The North Las Vegas airport (one of the most dangerous in the country) is not far (about 8 miles) but those planes also don't come this far North. There are mountains very close to the North, and more mountains just East of Nellis, so maybe that also discourages air traffic. Anyway...
I don't know what those military planes are doing, but it sure looks interesting. I see planes criss-crossing and all sorts of weird patterns of vapor trails. Sometimes I'll hear a plane (over the music from my earphones) but there will be nothing in sight. So it's a fun distraction, watching the skies.
