Lol, yes I would say there is a huge difference. I grew up in MA, moved to Florida in the 90's and immediately saw differences. Back home denim skirts, going without nylons, flip flop shoes, tank tops were all frowned up for even book study night. There were huge dance parties regularly held when I moved to Florida. Sometimes there would be a formal event up north, but nothing like the dance parties here. Wearing a one piece to the beach was not typical in SWFL.
Visiting California, I saw the same "liberal" JW attitude. Going back home to see my parents was always a chore as they disapproved of so many of the clothes (that were still modest) that my daughter and I wore.
Witnesses in my area in Florida were very open about reading Harry Potter, going to the movie and seeing Wicked when it was here. I'm not saying everyone in the hall was happy about the lax clothing "rules" or open entertainment ideas, but no one was ever counseled that would have been up north.
Just my experience.
My mom calls Fl Sodom and Gommorah for witnesses. Lol, the couples I was friends with were all okay with not having WT approved bedroom lives and the women had adult toy parties.
