I am glad of that. I don't want to have spent the day crawling up some long fire road to the top of the pass, to look down and have my view of nature spoilt by BRIGHT FUCKING ORANGE blobs of people below. The same when hiking. We talk about the pollution of littering, but there is also the visual pollution of our very presence. Imagine if you had hiked to the top of the mountain, only to find your view spoilt by some fucktard pitching a dayglow orange tent in the middle of your view.
Meh, it's not like most of the green stuff you see isn't in some way man-made. This country is supposed to be woodland or mostly underwater or whatever, not fields and hedgerows, grouse moors and so on, interspersed with all the usual car infrastructure that we're systemically blind to.
If someone's in a bright orange tent, it means they're camping, which is in my book a Good Thing. Maybe I'm biased because hi-vis orange isn't that far away from foliage green anyway.
On the other hand, I like dark-coloured kit
