copied and pasted what i sent to one of the other guys here for all, i hope they work good for you as well as him too.
now just keep in mind that i dove these spots before the hurricanes went through and have not been back there since, the vis was way too poor for my taste.
also i have noticed that people call spots by all kinds of names so i am not 100 % sure either of these are the actual "bone yard" i just know that a couple of people i know have called it that and i found a bunch of really good teeth at both these sites and also my largest teeth too.
the first spot is not too far from the pier , no structure just flat bottom of broken shells and teeth everywhere.
N 27*05.005
W 82*27.844
the second spot is a little north west of the first, there will be a small ledge with about a two foot relief near the center of the north eastern section. i found a few good teeth here and then moved over about two hundred yards north west of the ledge to another spot that was flat and covered with teeth everywhere and had alot of dark black patches with very good teeth and a few bones too.
N 27*05.050
W 82*28.004
i have also had some really good luck a hundred yards or so west from just between the two swim markers right off the venice public beach , i just went down right after i passed the bouys and kept heading west untill i got to the reef line then went over top of it to the west side then followed it south and i found a really big section that was all black crushed shell, rock, bone and a crap load of perfect teeth.
i hope this info helps you , if it does lat me know, if not, still, let me know, cause as soon as the water warms up to the mid to high 70's i will start going back out there again and if i find any new spots that are good, i will let you know.
good luck,
wesley
