Rope

So about a 10-15 meter rope.
What do you do with it?
This rope I ever bought for my kite. It;s as thick one (10 mm) but it was for a large kite, with wind force 4-7 it can tug properly.
I make the kite to the towbar of my car fixed and then the 1500 kg weighing 4WD will come with the rear wheels just short of the ground. So that rope is needed.
