9/11 Anniversary Weekend

Will Bush's Visit Interfere With The Anniversary Events?

I'm sitting here in my apartment, reading about how Bush is supposed to go to all 3 sites for the anniversary. I don't know how difficult it will be to get to Ground Zero because of his visit. Knowing Bush like I do, I don't think he would have a problem blocking individuals from getting there.

Any thoughts? Insight from locals? What have you heard about his visit?
