Gene; I'm told that the two casinos in the Marina District in A.C. (Harrah's and Trump Marina) also are sinking to some degree, due to the marshlands they are built upon. Like the skyscrapers in New York City, which are engineered to sway in high winds, I'm sure that some casinos are also engineered with some expectancy to "sink". Some of this info probably makes for good headlines in order to sell newspapers. Maybe Steve Wynn could consider building a replica of the Leaning Tower of Pisa Casino?
