"Sure, but I've read about people being attacked by mountain lions in much more populated areas. Whose fault is that?"
People, since they chose to purchase homes in housing tracts built right up to the edge of wild nature areas known for mntn. lion population. The out of touch people have the attitude of a child bicycling, walking and jogging without mace or a walking stick(club) to scare off an attack in such areas is very naive and ignorant.
Actually, the Mountain Lion problem has been exacerbated due to so many states outlawing the use of dogs to hunt them and keep their numbers down and away from populated areas...pretty damn hard to track and kill a mountain lion without the use of dogs...another one to thank the genious lib politicians for..!
