Rockdale volunteer firefighters answered two residence fires in two days Sunday and Monday. This 9:54 a.m. Sunday alarm called the RVFD to a trailer in Shady Grove RV Park on West Cameron (US 79) near the western cit limits. Fire Chief Warren Matous said the structure was gutted by the blaze, which is believed to have started in an electrical connection. He said the RVFD did not know who owned the trailer. At 5:32 p.m. Monday, volunteers extinguished a burning couch at 404 White.
