When I first moved to my small mayberry community in the Sierra Nevadas when I was 11 I saw a mountain lion about once a week. In highschool I was lucky to see one once a year. They were being wiped out. I believe it was an attack that happened in Yosemite (about 1 1/2 hours from there) that begin to drive the locals on a mad hunting spree. If they saw one they killed it and since it was usually on their property there wasn't really anything that could be done. When I was 9 in the community I lived before I took regular hikes out in the backcountry and once came within feet of one. If they were the horrible monsters that people seem to make them out to be I would have been killed. Attacks only happen when a female is protecting her young or one is provoked.
