The show started around 9:00 PM, and on the 23rd, the trail closed at around 8:35 PM to set up parts of the show. Since then though, the trail is closed for a much shorter time, and some people have noted that people are allowed through the trail, as long as it stays organized, although I can't confirm this until the next time I see it. There are new signs up by the entrance to Millennium Tunnel and on top of the new Frontier Trail sign that I described earlier. Overall, it was great experience and it will be something that I will try to get through most nights that I'm in the park. I was oohing and ahhing all the way!
