Colofornian, I don't think they will chit where they eat. They could spread out. Know what I mean? I don't think they will pull something close to their homes.
Never know, though. They are a bunch of animals with no brains.
I've thought of that. And that's why I said cities/regions. The thing is that security will already be high that day; therefore, long-range travel would be increasingly risky. Just as thiefs operate best on turf they've already extensively scouted (or grown up in); so, too, w/terrorists.
Contingencies work best on familiar grounds. Anything out of the ordinary occurring that would disrupt their plans is best detected in the landscape of their routine life.
Listen, these places they are at now were not chosen randomly. There was already existing criteria as to why they were chosen. And one of those criteria, was ease of movement. Note Orlando. Note other Florida tourist destination locations. Notice high-minority population areas & ease of border-crossing locales like Houston and Tucson. Al Qaeda was intentional in picking these areas.
