Thanks Grits & Mrs. S
It's pretty scary. I work in a building that sits on top of Grand Central Terminal and I take the subway. It's the subway we worry about when they're talking nerve gas and stuff.
The only comfort is the NYPD. Not many people know this but they've set up their own antiterrorism task force. 1000 officers are constantly checking bridges, tunnels and trains. They get international intelligence reports too. They're doing it because we can't rely on the federal government as you well know.
You're right... it does feel like there's no where to run, no where to hide.
