People also reported seeing emergency vehicles coming on the ferry to Crystal Beach.

At least one business decided to close up shop for the day as a safety precaution for employees.

KHOU 11 News spoke to some of those who camped out on the beach for the weekend event.

“It was the best weekend I’ve ever had in my life,” Zach Daley said. “We’re just out here partying, it’s non-stop drinking – it’s a good weekend. We’ve seen a whole lot of stuff. Get you some beads, gotta get you some beads.”

Daley and his buddy Pete Briones have been out here on Crystal Beach since Friday.

“One of the best experiences of my life – this is the first time I’ve been out here,” Briones said. “Yeah, I had a great time.”

Some people on social media said the party on the beach has gotten way out of hand.

“…how many people have to be seriously injured and/or die for there to be some changes made..,” wrote McKenna Sanders on Facebook.

Hundreds of people have signed an online petition calling for an end to the annual event.

Now that it’s all said and done – it’s time for the cleanup.
