lifelong former NJ resident here. i grew up in Paramus in the 1980s and lived there until 2005, but stayed in Bergen County until 2022. the area has exploded in growth starting in the mid 2000s and hasn’t really stopped since. i used to think blue laws were dumb but you never had issues navigating around Paramus on a Saturday until about 10-15 years ago….and it has only gotten worse. the roads and infrastructure weren’t built to handle the amount of congestion that exists now. my mother still lives in Paramus and never in her over 45 years living there has she had issues getting out of her own driveway. at least one day a week residents can get a break from all the traffic. it really is terrible (the traffic). it never was as bad as it is now. it’s great that the area is booming and all, and since i dont live there anymore i don’t really have an opinion, just my perspective on why people want to keep the blue laws.

edit: i now live in the bible belt and we don’t have blue laws and people can go to the malls on Sunday and do whatever. but the population is so much less so every day here is like a Sunday in Bergen County
