An investigation is under way into the cause of a fire Monday at Grey’s Point Camp-RV Resort and Campground in Topping that destroyed one weekend cottage and severely damaged an adjoining cottage. The Southside Sentinel reports firefighters from 4 companies contained the blaze by spraying water onto the roof of close-by cottages. Smoke could be seen for miles along the Rappahannock River. The cottages were believed to be vacant.
