Hi there,My dear old Dad is taking his boat to Tumby bay in about a weeks time and asked if I could please get hold of some GPS marks for him.Does anyone have any marks that they wouldnt mind sharing please? Of course I am not silly enough to expect anyone would share their secret spots but just some well known ones to give him a head start, me a pat on the back (and maybe a free feed of fish) would be much appreciated. Many thanks
