9/11 was a terrible, terrible tragedy. Now it is time to move on. By moving on, I don’t mean forgetting about it. I don’t mean turning it into a holiday, where it will become just another excuse to barbecue hot dogs and drink beer in the afternoon. I mean it’s time to put it in the same place as JFK’s assassination and the Challenger explosion. It should never be forgotten, but it can no longer be dwelt upon.
