Of course, once you reach downtown, the street lamps are aliens. And this is everyday, not just for the festival.
After the museum closes for the night, the festivities aren't over. There's still panel discussions, mostly about abductions and recent sightings. The city had an alien parade down Main Street. And, of course, you get to see things that are considered "par for the course". I'm going to try to get some of those pics for tomorrow.
