There are the most amazing lights there. They really get into it. There is a Christmas lights trolley tour that goes all through the historic district and downtown and then out to the grounds of the Passion Play. Of course, they don't do the performances in the winter, but they do the lights in the amphitheater and all around the grounds. They had the story of the nativity in lights that covered a huge area. Here is one that shows part of the amphitheater. I reduced the size when I first scanned it though, so you can't tell a lot.

Yes, I wish I could remember where I saw that article but the photos were wonderful. Natchitoches LA does a similar thing every year. That should be fun and I'll bet Tyler will just love it.
