Tutankhamun and the Golden Age of the Pharaohs opens today at LACMA. The last time Kig Tut's treasures were here it was a mega-event. The museum and the exhibit's promoters, National Geographic and Anschutz Entertainment among them, are expecting a reprise of Tutmania before the ancient Egyptian artifacts leave town Nov. 15. You need tickets to go, and more than 250,000 have already been sold. A casual day at LACMA it's not: adult prices are $25 weekdays, $30 weekends.
