GARY, Ind. (AP) -- Promoters of a planned Michael Jackson performing arts center and museum in Gary say they hope the project rivals Elvis Presley's Graceland in popularity.

Gary Mayor Rudy Clay predicts as many as 1 million people could visit the development each year. Graceland draws about 600,000 visitors annually.

But attendance at other celebrity-oriented sites is much less, and it remains to be seen whether the $300 million Jackson project would have the draw Clay hopes.

Presley's birthplace in Tupelo, Miss., sees only 75,000 to 80,000 visitors a year. The home of the Motown sound in Detroit that featured acts such as the Jackson 5 saw about 60,000 visitors in its 2009 fiscal year.
