Brett Coleman, owner of Coleman's restaurant, which is across the street from Fox Valley Systems in Cary, happened to be looking out the window when Wednesday's explosions happened at the plant. Coleman then saw office workers run from the building without their coats on and offered to take them into the restaurant. A few minutes later a Cary policeman came over and evacuated everyone.
