Many of us who do overnight camping trips will sure bring along ropes, strings and cords to set up ridgeline for flysheet and hammocks, pitching tents and tie guylines to the ground.
Usually, on the last day of the camping event, nylon strings and smaller-diameter nylon ropes that are still attached to tent or flysheet grommets are left untidied, in a rush to vacate the campsite. They may be left as they are (i.e. messy/tangled) or tidied back home using the standard rope care for coiling unattached rope (see pic 1 below).
