I grew up in Hunterdon County.
I can't speak to the crunchy factor now, as I haven't been back there in several years, and didn't have a crunchy family. We did live in a McMansion, and had TVs, LOL. I don't remember having a lot of Disney toys, but I can't imagine why kids would have more there than anywhere else if their parents wanted them to have Disney toys.
But our McMansion was unique (a contemporary in a subdivision of mostly colonials), and on 2 acres. My neighborhood was very safe, and in the summer, the hot air balloons flew over our house on a regular basis. The New Jersey Festival of Ballooning is held in my hometown (Readington) every summer, and it is much bigger now than it was when I was little, but the whole neighborhood would hang out on the best lawns to watch the balloons from, and it is still a fond memory of mine.
And yes, the schools are excellent. If my husband would ever agree to moving to Jersey, I would jump at the chance to raise my kids in Hunterdon!
I still know many people in the area, and several of them are crunchy. Lambertville is right across the river from New Hope, and I would guess the crunchiest area in the county, though I'm sure there are crunchy folk all over the place if you know where to look.
Like I said, it's been a few years since I've visited Hunterdon, and even longer since I grew up there (lived there from 1980-1994). But it was a wonderful place to grow up, and it is still one of the most beautiful places I have ever been!
