Despite the warnings to outsiders to stay away, tens of thousands of people showed up for an unofficial costume party that town leaders say they want to limit to locals only.
Town leaders say having thousands of outsiders show up overwhelms the police department, and could lead to a safety issue.
In an effort to control the crowd, police shut down streets throughout downtown. Besides the limited access, there was also no shuttle bus service, or parking. Plus, there are also alcohol checkpoints.
However, the restrictions didn't stop people from joining in on the fun.
"I'm from Vermont. So, I've never seen anything like this," said Natti Shaw. "I think it's awesome, closing the whole street down to get everyone to come on Halloween. To go and just walk around and see everyone else's costumes."
"It's madness and I love it," said Cabicha Turenchalk. "It's great. It's so busy, and so many people. It's awesome."
The annual tradition is expensive for the town. Last year, additional security costs totaled $184,000. No word yet on what it cost this year.
