I saw a cougar while riding my mountain bike in the Golden Gate National Recreation Area, just north of the Golden Gate Bridge. I called the park service to ask about it and the wildlife officer flatly denied there were any cougars within 50 miles. We talked about it for a few minutes and finally she said "OK, there's a female with two cubs there. Please don't say anything to anybody or people will be harassing her." So I think there's always some of that going on.
