I second the difficulty of finding PV the first time . . . . cross the Whitman Bridge and into the mysterious bowels of central Jersey.
You're getting warm if you see a waterpark, but if you get to Diggerland, you've gone too far.
There is a turn, but it is not really marked - and at the end of a woodsy road, you'll see a gate, except there is not really a sign.
I was so lost the first time, thought I must be in Delaware - rolled down the window to ask this guy at what looked like the entrance to a county campsite . . . . . . and Open Sesame.
*That* is the entrance to might Pine Valley?
Absent a GPS, better leave breadcrumbs if you ever want to find 676 to City Center again.
