Garth Brooks, the cowboy hat-wearing country singer, will play the USF Sun Dome at 8 p.m. Nov. 19. Martina McBride will open the show. Tickets are $17 and go on sale Saturday through Ticketmaster. A lottery system will be used because demand for tickets likely will exceed the 10,000 seats of the Sun Dome. The lottery also is supposed to discourage scalpers and prevent fans from camping in line overnight. At 8 a.m., people will be allowed to get in line; at 9 they will receive a number to determine their position in the ticket line. At 10 a.m. tickets go on sale.
