Rockwall (WBAP/KLIF) – Rockwall Police arrested a woman Saturday who drove her tractor in the town’s Fourth of July parade even though parade organizers told her they would not allow her to do so. They said Laurie Bostic was not able to control that tractor, so she could not participate. She drove that tractor into the middle of the parade anyway, refused to stop, and barreled down the parade route with police officers trying to stop her until she ran into a fence. The tractor was wrecked, and Laurie Bostic was arrested.
