I usually find people at melville fairly helpfull, thing is if its all they way down the point sometimes with kiting tunnel vision it doesn't get noticed...
Another kiter released there kite on the south end about 20m out from shore not sure what the reason was.... The kite was grabbed about 100m downwind luckily still on the shore didn't fly over the road etc but it did fly past about 5 kiters setting up who had tunnel vision in there own setup.
I was going to run after it but since there were so many people downwind I assumed it was ok
