Just a week after the Facebook event was posted, more than 2,000 people said they would attend.
Supporters spread the word on social media: Come out and help us stop Lake O releases.
TCPalm reporter Laurie Blandford was one of the first to arrive at Phipps Park, the site of the rally. She found Capt. Mike Conner of Stuart, who set up his boat with his wife, Patty, to join the protest.
Conner shared his rather unique message to Gov. Rick Scott with Blandford.
Expecting thousands, rally organizers urged attendees to carpool and arrive early.

Protesters began to organize, setting up their signs and booths.
