JACKSONVILLE, Fla. -- Deidre and her daughters enjoy riding horses.

"Both my kids compete. My 3-year-old and my 8-year-old, they both compete in junior rodeos," she said.

That's why Deidre saw no harm in riding to pick her daughter up from school on horseback, especially since she was trying to prove a point.

"I don't have the funds in my budget to sit in lines for an hour to two and a half hours to wait for my daughter," she said.

Deidre and some other parents are up in arms about a new parking policy at the Crystal Springs Elementary School. Parents are made to line up in their cars and their children are retrieved by the staff one at a time.

Deidre said it's a lot less expensive to wait on a horse. But when she arrived at the school, she was ushered off the property by police.

"Our first priority is the safety of our children, and during our arrival/dismissal, their safety is first and foremost a priority on campus," said Principal Jaime Johnson, who is new to the district.

Johnson said the reason she didn't want Deidre and her horse on school property was that it posed a safety issue, but Deidre said horses are gentle and wouldn't harm anyone.

"(Johnson) would not turn loose of my daughter's hand," Deidre said. "She proceeded to pull my daughter back and squeeze her hand."

Deidre said that even when she saddled her horses, the principal wouldn't release her daughter. What she didn't know was that Deidre had driven the horses in a trailer to a friend's house three mailboxes away.

An officer drove Deidre's daughter home, where she waited alone until her mother arrived.

The school and parents have yet to resolve the issue.

Deidre is most upset that her daughter wasn't released to her, but Johnson said that given all of the construction around the school, she didn't think it would be safe for the student to ride horseback on these streets.
