I don''t see what the problem is. what you posted is very true, and in an ideal world that may work, but the end result is they get in a tangle, they spend 15-20mins fighting with said tangle until you can get to them (cos their about a mile downwind of you), and when you DO get there, all they want to do is cry and go home, cos their cold.
not that I'm speaking from experiance of course. locally we have a lady now interesting AND she bought a kite, shame, its only been out ONCE though:rolleyes: and that ended up in tears and I want to go home, I'm cold, followed by make up to you food etc etc:)
