I'm not too familiar with Lodi itself, but how close is the California Aqueduct to town? Since that aqueduct provides water for the San Joaquin valley, that might seem like a potential target of these creeps. I'll be interested to hear about the Rancho Seco info too.
I'm honestly a little dismayed that FReepers seem more concerned with a confirmation hearing or the stupid Jacko trial than this story. Usually we are on top of such threats compared to most people, but if even WE are distracted by this other stuff...well, it makes me concerned that we are getting too complacent in this country.
