Not at all: it doesn't mean anywhere, anytime; it means very specifically places where children could reasonably be expected to be present.
I think that it's not an overly technical legal term. I think we can all envision examples of where children could reasonably be expected to be present. It wouldn't be in an after-hours bar at 3 a.m., but it would be in a schoolyard. It would be leaving church, or a shopping mall, or a ball field, or a rink. It could be leaving a hotel at certain times of the day.
So it is a common-sense, practical application of a definition that we think the courts will uphold.
