I dont think that thats a real thing now. I see some pictures of women in hijabs trying not to drown interspersed amongst men with unusual fashion sense fishing.
Looks to me like a get together for the guys to signal who wants their bomb bay expanded.
I dont think there is much in the way of wine and dancing going on, at least not among the women.
Yeah, it was still a thing unless a fundamentalist family went to the beach.
