While I'm not so sure just how close I'd want to get to one or more, as a life long musician, born to make noise, i d love to interact with them sonically, through progressive mimicry, with increasingly complex sequences of sounds. I'm not sure about a percussive side, as I don't know to what degree meaning is transmitted through their various patterns of wood knocks, and like call blasting, "if you dont know what you're saying....don't yell it!". But I've always dreamed of an " odd noises in chains" sorta interaction.
As was said earlier, running into a big male in relatively close quarters would freak me the F@#k out. I had a scary incident as zookeeper with a very quiet and very sneaky big ass polar bear, where I turned around with my face about 1' from its white bear belly, with a chain link fence inbetween, but at that proximity, my brain wasn't seeing the fence, my primal self saw fur. I looked STRAIGHT up to see the front half of the bear with its paws in a "hands up" position on the top of the fence, as it looked down at me with a "if it weren't for this fence, little monkey..." ( Ok, in hindsight it might have just been "Gotcha! You should see yer face, pinky!" )I just about fell over dead right there!
but if it were a graduated approach that didn't seem rife with hostility, I could see getting fairly close to a smaller to mid sized sasquatch, if my legs still worked......and they made neat noises!
