I also think the fact that want the range to be family friendly adds to some of those rules. Modesty used to be common place.
I agree, what happened to going out in public dressed appropriately? I see people walking around in sweats and boxer shorts and it bugs the crap out of me, the worst though is pj's and house shoes. HOUSE SHOES ARE EXACTLY THAT SHOES THAT ARE TO BE WORN IN THE HOUSE NOT IN PUBLIC!!!
