It's more than that. I am genuinely HAPPY to see tourists here now, because right after 9/11 I didn't think anyone would ever come here again that didn't have to. It's like a vote of confidence when they travel here now. I want to give them all hugs. And that is NOT normal. :D
Frankly, I don't think New York is as desperate for tourism as some people make it sound. Naturally, the events of September 11h dampened tourism to NY, as they dampened air travel in general. But I think that's just a normal and temporary reaction which is fading as we speak. I have no doubt in my mind that NY will bounce back from this just fine.
