There's no doubt the Greenbrier Resort will see a lot of people on their grounds the next four days, and some local tourist attractions hope to see their fair share.  The Greenbrier County Conventions and Visitors Bureau says they expect the majority of Classic attendees to arrive Wednesday evening.  Some expect golf fans to take some time during the four day tournament to visit area attractions.  "We're definitely hoping the downtowns will see an influx of people, downtown Lewisburg and White Sulphur Springs especially," says Kara Dense of the Greenbrier Co. CVB.  She also believes some will check out places like Lost World Caverns near Lewisburg and Organ Cave near Ronceverte.
