Castle Rock residents might have seen lots of flames and activity at 145 B Street SW on Saturday, but they didn’t have anything to worry about. The structure at the address was part of a previously scheduled “training burn” for Cowlitz County Fire District 6 firefighters. The house that was burned was across the street from Castle Rock United Methodist and Castle Rock City Hall. “This opportunity allows the necessary training to keep our firefighters safe and up to date on the current fire standards,” said a Facebook post from the district’s website.
