Some you need a rope and others you do not. Climbers usually have no trouble at all in the slots because they are use to the rope work and breeze by the little downclimbs. There are also many slots you can visit that don't need a rope or climbing skills.
Does that mean you had a 600 ft rope or did several pitches. Do you folks use static or climbing rope?
Bo sets up the ropes when we go, but 600' of rope would be a pain to carry. Most usually bring just enough for the longest rappel. The rope usually used for canyoneering is made special for it.
