Sorry- I thought I had responded to this thread. Was there another one on here about it? I was tagged by about a dozen people on Facebook with the story, and I responded to some of those threads, so I thought I had on here.
I have never hiked that canyon, but it is very close in location and very similar to the dozens I have hiked. I don't know what I would have done . . . after shitting my pants. I would have grabbed my GF's hand and raised them up to make us look bigger and more dangerous. I kept thinking to grab big rocks and throw them, but I would also be scared that it would attack once it saw me get small and take my eyes off of it to get rocks.
I had a discussion with a couple of other guys about this video: if push came to shove and you had to fight it, would I be able to survive? I am very confident that I'd be fine. Even if succeeded in latching on to me with its teeth/jaws, I'd be strong enough to gouge its eyes, punch it in the head, etc. to the extent that it would release and retreat.
I'm not saying that I'd come out unscathed void of some nasty claw marks and bites, but I am confident that I'd be able to fend it off to the point where I wouldn't die (excluding some freak bike that popped a jugular or something).
