Don't think you are very close to these places, but one is in Florence Township and the other near Delran. In Florence Township you can google map search on Roebling Park. It's right on the Delaware River and directly accross the river are a set of lakes (on the PA side). Nice to fly over Delaware and then over the lakes (very scenic and wide open). The other spot near Delran is off Rte 130 near Bridgeboro Road. There is boat launch opening along the Rancocas Creek (which is fairly large) where you can fly straight out and fly along the creek with boat docks and even a golf course along the way. Also very scenic and wide open. How about you, any places you know of that you find especially interesting.
I have video of flights at both spots I mentioned on YouTube if you wanted to check them out.
I like to fly over northern Barnegat Bay near the Mantoloking Bridge. There is a heliport listed for Barnegat Bay Marina but just call them and they will let you know if its being used. I have never seen it used nor are there any planes ever landing on the bay nearby that is seen on B4UFly. I also fly over the eastern Metedeconk River, the Mantoloking Bridge and east to the shoreline. Beautiful.
