I’d be looking at San Diego.
The Coronado Bay Bridge would be a tempting target to the Jihadis because of it’s numerous access points from the San Diego side and it’s strong military presence on the Coronado side.
I think they’ll be after quantity, rather than quality this time. Multiple targets would be likely. I know they’re stupid enough to go after schools. Might be their undoing here. Hard to tell. We seem whipped, in a way.
I think the Verrazano Bridge would be too, if this is credible.
