Sand and rock-filled socks hurled at vehicles in Cobb Co.

KENNESAW, Ga. (AP) Authorities are trying to find whoever is throwing socks filled with sand and rocks at motorists northwest of Atlanta. <br /> <br /> Drivers say they suspect the projectiles are being hurled by someone hiding in the woods near roads in western Cobb County. <br /> <br /> Murray Chalmers tells WSB-TV that he was driving after dark Monday when something slammed into his windshield. He saw a couple of young men in the area, and didn't immediately realize what had happened. <br /> <br /> Another motorist, Allen Ashwege, thought he hit an animal over the weekend and then found a sand-filled sock imbedded in the front grill of his vehicle. He returned to Kennesaw Due West Road and found several other makeshift devices along the road. <br /> <br /> Police say they've received several similar reports and are tracking down leads. <br />
