hay sam you did well to untangle yourself. You got to the kite ok and the lines were running freely around the beacon. You can self rescue by using the kite as a sail, it is not easy as some would have you believe but you can do it, especially if you let some air out of the leading edge so you can bend it a bit.
I had a chat with pauli and got the gist on rescues like that, it is not easy untill you see it done.
Remember as someone used to keep telling me when i started 'distance is your friend' and do not worry you can not be as dangerous as Johno is

, or as exciting as'mad dog fitzy'. Then of course there are my own adventures. In fact if you ask around you will hear almost all have tales of wow.
