Jag, i might dispute your choice of words:
The old bucks are normally frightened badly by the smell of humans in the woods.
I don't think frightened badly is the exact right phrase. I.E. More cautious disgust than fright
More likely they think along these lines, " Oh, crap here come those azzholes again to fug up my day. I'm just gonna hole up and let them stumble past. They stink!"
