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.
