Salem, Oregon, U.S. - Three newly-constructed upscale homes were vandalized with pro-environmental slogans which read: "Stop building ant farms," "E.L.F.," "Rent is theft," "Viva E.L.F." and "Don't kill my air." Additionally, a window was broken. E.L.F. stands for the radical environmental Earth Liberation Front. According to authorities, this is the second time within the past two years that ELF vandals struck in this neighborhood.
