The point about human/animal noises and the difference in how you react to them is a good one.
One of my favourite spots is awash with red deer, and they are noisy types at the best of times. It gets I dont really register their howls and scowls at all, I just get my head down.
However, about 6 weeks ago I was out, and awoke with a start because my brain registered very human noises. Shuffling. Clanking of kit. Puffing. I looked up, and about 25 yards away were four guys, all had crossbows. Big, nasty wheelie bows at that. This is 04.30, about 4 miles from the nearest road, and that has passing places becuase it's so crap. We're talking real middle of nowhere here. They walked about 2 yards in front of my basha, and thankfully never saw me.
I admit though, that at that point, I was experiencing a helluva adrenaline rush. Not scared, but very apprehensive. Nice people dont traipse through the woods in full kit with section 25 weapons at dark o clock in the morning after all.
The point of the story is, that that experience, though a fright at the time, it was easy to deal with because its a quantifiable threat. It's the other type of experience, where something isn't right, and you can feel it isn't, but there isn't a physical form to identify and threat assess, that are the ones that scare you. I've had them and though very rare, they get to you at a whole other level. Real frog part of the brainstem stuff. While I'm not educated to the level of some who post here, I do have a science based degree and feel I can reason most things away fairly well. Some experiences however, you just cant. Those stay with you.
If you've never have the latter, good for you. If you do, you'll know exactly what I mean, and I dont give a toss how 'hard' you think you are. It doesnt help.
Until then, certain posters would do well to gain some maturity and don't rubbish another mans experiences.
It might make you think you look good, but it really doesn't.
