Spotsylvania (WFVA) -- Spotsylvania Sheriff Roger Harris says any fireworks that propel into the air are illegal. Sheriff Harris says watch out for sparklers. He said the sparks are "hot and dangerous." Sheriff Harris said sparklers in dry grass are also a fire hazard. He said once the sparker is finished the "metal rod retains heat." Sheriff Harris said the safest way to do fireworks this week is to let the professionals entertain you.
