Because if you don’t use a torch you will be rewarded with sights and sounds that will leave wonderful memories that last a lifetime, sights that you would never have seen if you were using a torch and sights that the daytime only wanderer will never see. To be out at night seeing the countryside bathed in moonlight, using the shadows to get close to wildlife, noticing the silhouettes and skylines, watching white cloud drift across the nightsky on a brisk wind, and all accompanied by the various night sounds, is a real delight. Shining a light will scare any wildlife away, even a dim light can be seen from a long distance. I have many times crept along the shadows of a woodside watching deer/badgers/foxes/rabbits & hares in an adjacent field bathed in moonlight and approaching with a torch would have scared them away long before I ever got close to them, likewise I have many times glanced up into the trees and saw various birds silhouetted against the sky, a torch would have scared them off too. At night the more you use a torch the more you will want to use a torch, the second it’s turned off everything seems really dark and it tempts you to turn the torch back on again. If you want to just bash along or run or if you are a clumsy walker then a torch may be useful, however if you are observant and walk steady and you want to savour a wonderful experience then a torch can be a hindrance not a help. It doesn’t stop you carrying one in your pocket for emergencies.
All sounds very romantic.
Not sure how romantic it would be if you tripped, broke and ankle and was laid up in bed for 6 weeks though.
It's not like you can't have all of that with a torch, as i say it's not like you're suddenly immersed into a tunnel the second you turn the torch on, you still have peripheral vision, you can still see " silhouettes and skylines" and "the countryside bathed in moonlight"
I have lots and lots of great memories hiking at night with a torch, i think you are dramatising the effect a torch has, i've spotted everything from foxes and hares to beers with a torch it really is no less romantic than you are describing without a torch.
It's not a white/black choice either, on a bright cloudless night on a mountainside it's pretty amazing how well you can see.
On a dark cloudy night in the woods it's a completely different matter though.
As Julia said the trips are woods based i think it's important to make that distinction.
It's also telling that personnel markers are needed, if the vision is good enough to walk without extra illumination then in my experience it's bright enough to spot the guy/gal in front of you even 50m+ away.
End of the day we are all adults here and do our own risk assessments based upon our experiences and knowledge.
For me personally given the parameters in the first post i think it's dangerous to walk without illumination, this is based upon my own personal experiences of trying it.
So i thought i would voice those opinions and experiences so Julia could take them on-board, or completely ignore them as she wishes.
