Police Car Lights
This was taken during the Boerne Dickens on Main Christmas parade on Hauptstrasse, right around Red Crest if I remember correctly. You can see the snowflake decoration around the streetlight in the background. The police cars were blocking off the end of the parade route, and I had plenty of time to take 30-second exposures.
The cops were very nice, and although I didn't ask, a few of them saw me balancing the camera on a coffee cup and tried not to walk through the shot. They wanted to see it when I finished, and thought it was pretty cool.
