The NJDEP Geographic Information Systems (GIS) division has a very good on-line mapping website that you should take a look at...
Then hover your mouse pointer over "Interactive Mapping" and click on "i-MapNJ DEP"
A pop-up window will open explaining all about the mapping application.
To physically open the application, click on "Launch...i-MapNJ DEP"
The first layer that you should turn on (by checking the check-box for visible) is "Open Space (State)". This data layer includes all the State-owned public land. If you click on the "identify" button at the top of the mapping viewer and then click on the various (green) Open Space lands you will see the name and use of the land.
Also note, the various mapping layers have pre-set visibility thresholds. The closer you zoom-in, the layers will become visible. The 2002 color infra-red aerial photography is one such example.
I took a quick look in your area...you might want to check out Saw Mill Creek WMA. I would be willing to bet you would have Black Duck in that area at first light. Set up on the edge of one of those water passage cuts in the marsh. I would use a boat. You might be able to launch at that little place called BELLEMEAD PRESERVE on BERRYS CREEK right where it meets the HACKENSACK RIVER.
The manner in which I described above should give you some insight into how I go about looking for places to hunt.
Also, if you are just starting out don't think that you NEED decoys, a call or a million other extra's. Do you decoy deer in NY? Probably not...you do your homework and pattern the deer or atleast take educated guesses. Do the same for ducks. Camoflauge is good though. You don't want ducks flaring away from you out of range. If you take that 12 or 14 footer, do something to help your boat blend into the marsh.
Give it a try man...Good Luck!
