To be fair, the Loch Lomond pi$$ups were a thing 35-40 yrs ago when I was a lad, but I've found human waste and dirty bog roll in some of the most beautiful places in the Highlands. From a purely selfish point of view I've always hated the concept of the NC500 from when it came in, I knew it would ruin the highlands, but am aware that there are people depending on it. To my mind, plenty of the people travelling there wouldn't even pay for a campsite if it was 50p, so my policy would be - Yes, ban all MOTORISED free camping on the route, provide FREE campsites at regular intervals with toilets, showers and disposal points, maybe even small shop/cafe in each one. But permit all tent camping away from the road, they musn't tke away the right of people to walk the hills and camp part way to allow them to carry on the next day. To force people to only walk as far as they can get there and back in one day would deny them access to some wonderful places, as well as putting them at risk of exhaustion for walking too long and making mistakes resulting in injury. Maybe even ban motorhomes a certain size too, I'm sick of Youtube videos of people driving 7.5-8m motorhomes boasting how they were able to transit Applecross without problem - yes and how much did you ruin it for all the other road users, or parking sideways on a space which would hold 3-4 small vans and then staying there the week.
