Not a Griz, but had that Oh Shlt moment when I was fencing. Following along a fence that dropped down across a slough. Got to the bottom and it was overgrown with brush. Little tunnel opening in the brush running alongside the fence. I get down on all fours and proceed to crawl through this tunnel. In the middle, ground was real soft, a bit wet, I look down and see as fresh of a cat track as I've ever seen. Simultaneously I about shlt my pants, hair stands on end, I look left, right, up, down, forward, back a few times. I have nothing but a pair of pliers on my hand. My mind goes in hyperdrive and I think wtf am I doing here? FMR, I scrambled my a$$ out of there pronto.

Never saw it. But it damn sure woke me the hell up at that moment.
