Surprise Shower

It is raining here in Las Vegas. It doesn't happen very often, so when it does, I'm surprised. More surprising, though, is the lack of rainbows. I feel like there should be rainbows galore considering that it always seems like the sun is behind the rain. The dark clouds are almost always lined with the bright seam of light from a nearly irrepressible sun and the field of vision is vast. Still, I've never seen a rainbow here. I'll keep looking.
