when I was on the tril for wo days alone, I would wince at every noise other than my own footfalls. If I had flushed grouse, goodness knows I would have had a heart attack and lan there on the trail for days. In the words of Bill Bryson: "So woods are spooky... there is something innately sinister about them, some inneffable thing that makes you sense an atmosphere of pregnant doom with every step... Though you tell yourself it's preposterous, you can't quite shake the feeling that you are being watched... Whatever mechanism within you is resposible adrenaline, it has never been so keenly polished to pump out a warming squirt of adrenal fluid. Even asleep, you are a coiled spring." Does anyone else get this and is it different when with a group?
