The feral hogs that are such a destructive nuisance in Texas are spreading to other states in large numbers. The hogs have reportedly increased their range from 17 states to 38 over the past 30 years, extending as far north as Canada. What's worse, wildlife scientists believe they're being deliberately taken to other parts of the country in order to be hunted for sport. The fast-breeding hogs destroy crops, damage wetlands and habitats, and occasionally attack people. A woman was killed by hogs in Anahuac in November.
