Adam there is an entire city being built between the Monte and Bellagio. See below..........(This was taken from the NYNY parking garage..Notice the edge of the Monte on the far right of the pic. The majority of CC can't be seen from this pic)

This pic is a couple months old now. (I'm slacking on the City Center pics). They are in full blown construction on this site now. Not only that, but they are also doing a good bit of work on the Monte itself. (No pic, but take my word for it, we went by this weekend. Am also a Union Electrician working right across the street from the CC).

Dust, oh yea. 1 firehose on a site this big does NOTHING!! Round the clock construction, you bet cha! For the next few years I would not stay at the Monte. But hey, it's Vegas, WHO SLEEPS HERE???
