Yes, at least at times. I'm not too concerned when I'm in my "research area" or in other parts of this general area. I know I'm watched, followed, occasionally on the losing end of what seem to be practical jokes / pranks. I think if I were in danger there I'd have turned up missing long ago. They're only there when safe food is plentiful. Other places I'd be more calculatingly cautious at least until I learned the vibe / ground rules of the place.
I don't care for finding cougar or bear tracks in my tracks when I return. That puts my hackles up much more than BF does. And now we have wolves in increasing number / increasing distribution, some that have learned to overcome / ignore human hazing. Bigfoot is the least of those worries.
