Indeed. Good point. In fact a few nights ago when I walked out of my house in good ole upstate NY and heard in front of me the very distinctive growl snarl of a very big cat, and albeit while I was not attacked, the sentiments were expressed.

Had I been perhaps a bit smaller in structure or NOT waking out of my well lit home, for example if I was just strolling on a path near my home, an attack could hardly be ruled out... believe me that loud, deep snarl growl made the hairs on the back of my neck stand up to attention!

And others nearby have had their BIG farm animals attacked and/or killed by something with very BIG claws.

So I guess along side those other two JUNGLES you might want to add upstate NY and jogging/mountain bike trails in CA.
