I would not install a steel plate roof on my home because of a meteor hitting somewhere on the planet. But the fact remains that mountain lions are moving back into areas that have not seen them. ( maybe at least not in my lifetime).
I will continue to pack protection and will add bear spray to my personal arsenal.
I value all animals and consider all living creatures beautiful and worth preserving. But if it's me or them or I feel eminent threat to me or mine, I will react.
I appreaciate all the good info, opinions and facts on this subject and have come to the conclusion that humans pose a greater danger in the wide open spaces than animals.
Be safe out there and cause no harm...............if at all possible.
