Weinberg’s tour of the casino was like a Robert Altman tracking shot, a parade of workmen on scissor lifts, gardeners planting shrubbery, engineers adjusting lighting and testing audio, regulators testing slot machines, cleaners polishing chrome, dealers undergoing training at gaming tables, and waiters carrying glistening plates of food out to pose for a photographer. The casino project generated 3,000 construction jobs and will create 2,000 permanent jobs, and it seemed all of them were at work on Thursday.
