There have been several incidents in the Houston area lately:
Sept 26, New Caney, Tex (30 miles NE Houston) inspectors suspect foul play in pipeline explosion
Aug 19, 40 miles NE of Houston, natural gas explosion in underground storage facility
Aug 2, Texas City, Texas, at Marathon Ashland, explosion
There are several underground storage facilities in salt domes in the Houston area and across to Louisiana where the government stores petroleum (SPR/Strategic Petroleum Reserves)
I don't have access to all the FReeper posts regarding suspicious incidents in the Houston area involving refineries and pipelines. Maybe someone out there does.
Thanks for that info. You are correct that Texas has seemed to be on the terrorist "radar" for some time now.
