I'll not sure the Ivana tower will actually get built - it may be a petty slap at Donald, whose previously announced (and shorter) tower has already sold out. But the high-rise trend in Vegas (as opposed to the wild overbuilding in the suburbs) may remain viable for a long time - there is a lot of Asian money flooding into the market as high-rollers are buying permanent bases of operations for their gambling trips.
I cannot respond intelligently about Los Vegas. I have never been there and have no desire to visit. My Grandfather used to own a casino in Carson City and taught me to count cards when I was only five. I have never been much of a gambler either. I have been to the casinos at Lake Tahoe and seen Asians throw down small fortunes in a few minuets. They are among the worst gamblers in the world. Just what Los Vegas -- Triad Bosses mixing with the bent noses of little Italy and ex-KGB Russkies from Moscow. Ivana Trump should be proud of her contribution to world peace.
