Quite. And then you have to add yours to actually go down. It makes it very problematic for beginners and people learning to rig. This is the tradiest of trade routes and trivial to rig - You can stash your pre-knotted rope in a bag somewhere and show your maillons more love.Ireby at the minute has two ropes in situ at several points.. this photo is how I found it.
Swinsto has traverse lines and a couple of ropes labelled JSMT Ripon.
This does seem to be an increasing trend..
Basically in some of these cases it’s often more dangerous to rig your own rope on top! The likelihood of this older tat failing is still quite small, but I’ve seen lots of reasonably competent cavers get themselves tangled in rigging.
JSMT is probably the Army. Joint Services. A quick call to express disappointment to the relevant officer in Ripon from someone sounding official (CNCC) would prob elicit a response and a bollocking for someone. They are good at the latter, it’s the default action in all circumstances.
