Yeah, I'm not getting what the big deal is either. I think the OP probably does not travel much outside the U.S., where magazines with nudity, etc., are commonly read (and sometimes even distributed or sold) on trains, planes, the subway, etc.

Just another one of those neurotic overprotective parent things, I guess. There was a highly contentious topic here in TravelBuzz a few months ago where some guy was insisting that hotels get rid of PPV porn channels or whatever so his kids don't accidentally see a few seconds of porn. It's a hot button issue with some people, apparently.
