Where are the sunflower fields in PA?

A couple years ago I was camping somewhere near Stroudsburg, PA. On my way back to Central NJ, but still in PA, I came to a place where there were farms with hundreds of acres of rolling hills of sunflower fields along the county road. The sunflowers were about 8 feet tall with large blossoms. It was very picturesque because all of them were facing the sun.

Can someone please tell me where this place is or where a similar place is in NJ or PA? I want to go back and take photographs if they are still in bloom.
