Great Twistie Roads With 2 Hours Of Nj/pa/md?

[40Yrold]

I live in NJ/Philly area.

The types of roads I like to ride
Twisties
Elevation changes
Minimal police
low traffic

I found a nice 11 mile route over by the brandywine creek which goes into delaware, then back into PA at kennett sq.

Any suggestions for some other good roads?

The farmland stuff over in NJ where I live is mainly straights and right angles at the intersections.

Thanks!
