I cannot possibly watch every cable and broadcast news channel at once, but I am pretty certain they are saying essentially the same thing about the big Thanksgiving Day parades in some of the nation’s major cities.

Security is tighter than ever at them all.

This is a sign of the times. This post-9/11 world of ours has alerted us to the dangers posed by international and domestic terrorism.

They have presented themselves in horrifying ways, with goons running over spectators with motor vehicles. They detonated explosives. There have been stabbings and shootings.

New York City and Philadelphia are staging big parades today. The rest of us out here in Flyover Country will watch on TV — and many of us will hold our breath that we can get through this happy day and give thanks that tragedy doesn’t strike.
