Nic my whole previous post is parallel to yours. I do see it from the land owners point of view. Bolts and bouldering tend to bring more people that die hard trad climbers hence the problem with defacing of the rock with chalk (not bolts) and trashing of fynbos and yellowwoods. Check out De Pakhuys next time.
Clmbers have no right to trash any land including public land. But the farmer then also should no allow the natural stuff on his land be trashed by climbers to make a few $. It works both ways.
New Areas. New routes. Retrobolting. Add-ons. Re-grading. etc.
