If you're in Australia, beware of deadly watermelon-sized pine cones

As if Australians didn't have enough to worry about from their deadly fauna, now their flora are out to get them as well. The town of Warragul, Victoria, houses a 120-year-old bunya pine whose pine cones are the size of watermelons. The behemoths weigh up to 10 kilograms each, and, the local council warns, can leave a nasty crack in your head if you happen to be under one when it falls. So if you don't intend to wear a helmet everywhere you go, it's a good idea to look up occasionally.
