cast netting bunker from the shore

Hey guys - I've been trying to castnet some bunker for the past few weeks and have been failing miserably. I have the toss down, but I just can't seem to locate the bunker. Will I have a shot tossing the net down near RM backside near the demo 4x4 entrance, or do I have a better shot looking at local marinas like wantagh park or something like that. Any help would be awesome..or tips for using some kind of attractant or anything at all guys. I'm failing miserably and need some help.

Thanks - Joe
