Paul, check the schedule on the JPNEWT web site for future events that may be close to you. If there is nothing there now, check back from time to time for updates. http://www.jpnewt.com/tour_schedule.asp
If you don't mind a little travel and you want to see the best players in the world, make a trip to Chesapeake, Va. in October to see the U.S. Open 9-Ball Championship. http://www.usopen9ballchampionships.com/index.php
