Saturday’s house fire on CR 446 in the Salty area, between Rockdale and Thorndale, brought out four units from the Rockdale VFD and one from the Thorndale department. Heavy damage was reported to the James Hilton home. James McQuinn, assistant RVFD chief, said cause of the blaze remains undetermined. He said the fire began toward the back of the residence and burned much of its center. Neighbors said no one was home when the fire began.
