Keep the Republicans Out of the Tunnels!

Security is tight at Madison Square Garden. (At least, for anybody important) Access to the train stations under the Garden (both subway and Amtrak) is quite limited.

This is especially worrisome in that Al Qaeda has expressed interest in the same scenario ...
