(Beatty, OR)  --  The Oregon State Fire Marshal is sending additional structural crews to protect houses in Klamath County as the Bootleg Fire continues to grow.  Fire officials say the blaze has now burned 16-thousand acres.  Three task forces are being sent from Yamhill, Marion, and Polk counties.  Two strike teams are also being deployed from California.  Officials say the hot and dry conditions in southern Oregon will cause the fire to spread rapidly.  The fire is burning about eleven miles northeast of Sprague River.
