I worked in the chemicla plants in south east Texas. They are not armed, and generally are more concerned with theif then securing from outside threats.
I used to date a little cutie from Lake Jackson. Her daddy was a chemist at Dow Chemical in Freeport. I wonder if that is the same plant under different owners?
I guess it is possbible this is not terrorist related but darn, why did they go out of their way to say that?
