BRUTON'S BIRTHDAY WISH

Las Vegas Motor Speedway owner Bruton Smith celebrated his birthday on Friday at Piero's Italian Cuisine amid reports that he could get his wish soon for a second NASCAR race here.

Smith's purchase of the New Hampshire International Speedway in November would allow him to move one of that track's two NASCAR races to Las Vegas.

Smith was joined at his birthday bash at Piero's by family and friends, including film legend Ernest Borgnine; racing icon Carroll Shelby; Las Vegas car racing honcho Mel Larson; and chairman of the Vegas Entertainment Network Charles Ison and his wife, Jan, who hosted the dinner.
