New ballpark is another draw for thriving downtown in Summerlin, Nev.

On April 9, the Las Vegas Ballpark, home to the Las Vegas Aviators Triple-A baseball team, opened in Downtown Summerlin, Nev. The club and ballpark are wholly owned by Howard Hughes Corporation, which claims this is the first minor-league ballpark in the U.S. to be built within a master-planned community.
