The guy who owns the land the WTC used to be one said he's going to put up a monument in that area. He hasn't said what yet. Seems like a nice guy though. Lost a few of his employees that day.
To leave it how is it just seems weird. It's one hell of a massive area left there. Might be nice to have an open area amongst all those buildings though. Maybe a grassy field with a monument of all the names of those lost that day. Just a thought.
