@tralala1 People don’t care about how you’re dressed or where you go for vacation as much as they do in New York. People wearing last-years style and going to their in-laws in St. Louis for Yom Tov is not something that even elicits a passing comment.
There are no Chassidish schools. Just one playgroup and it’s only for members of the Chassidish kollel. The closest thing you’ll find to a “mainstream” school is Torah Institute for boys and BY for girls. Both have a larger variety of backgrounds than you may expect in NY (like, kids with TV and also kids who’s parents learn in kollel for life), and they are excellent schools.
Beazer is a Maryland goyish developer that built a huge development next to the frum community. It was the In place for a while, but it’s kind of Out these days. A Beazer house will still run you 600k for four bedrooms and an unfinished basement, and they are almost impossible to get. Summit Park is very In and just as close.
