SILVER SPRING, Md. -- If you own fireworks in Montgomery or Prince George's counties, fire authorities have two options for you: pay a steep fine or go to Six Flags Great Adventure. People who get caught with fireworks, even sparklers, could face a $1,000 fine and six months in jail. But with July 4 fast approaching, both counties are offering an amnesty program -- trade in your fireworks and receive Six Flags coupons. Pete Piringer, spokesman for the Montgomery County Fire and Rescue Service, says last year alone, 12,000 fireworks were turned in to fire investigators.
