Well I also have never seen a mountain lion, but my brother two years ago swears on our mother that he and a buddy of ours saw one while turkey hunting. I saw them about 20 minutes after they saw it and I believe them 100%. We were hunting the the Catskills of NY. Two other people in the area have also seen the same thing. When the DEC was contacted they said that it was most likely a bobcat or a deer. We were totally blown off. Now I think that they are probably extremely rare, but I think it is possible for them to be a few of them still in the east.
