ave you ever thought about the risks Hi you take when you travel? We have all heard horror stories of missed flights, lost luggage, train delays and traffic jams but have you ever heard about snakes? No? Well, here's a story that will make you think twice the next time you fly, It all started one day when a passenger boarded a flight in South Korea with a little 'something' extra in his luggage. However, he didn't declare what this something extra was when he left South Korea, When he arrived in Atlanta, USA, customs officer Christopher Hendericks checked the man's luggage. To his surprise he found 30 snakes in bottles! He also found some bird specimens in the bottles, and a special liquid with the snakes and birds to preserve them. Hendericks said, "I've found snakes before but what surprised me about this case was how many there were. At least no passengers were hurt." Even though the reptiles and birds were not alive, there was still a problem. As the US Fish and Wildlife Service stated, "It's possible that the dead snakes had poison in them. The passenger even put scorpions in the snakes' mouths. So, we had to check all the animal specimens in the bottles." The airline did not release the name of the passenger. The police charged the man with breaking the law twice, once for not declaring the strange contents of his luggage and once for importing endangered species.
