Steve Wynn toured Everett, Mass., on Wednesday to view a possible casino site on the Mystic River. "I remind most of you that in my business the development makes the destination. The kind of facilities we build become destinations unto themselves," Wynn said when asked about probable customers of the planned facility. Wynn, who didn't make any definite commitments, said that discussions with the city are preliminary. "Massachusetts has become very interesting to my company," he said.
