I will say that the likelihood of school trips in public schools is possible, but significantly fewer and less likely than for home schooling. A home schooled child can take a field trip every week. This will not happen for public school student, just for logistical reasons.

My point was to counter the argument that "they [home schooled children] all lack an awareness of the real world". If you look at my response from that context, it is clear, at least to me, that a public school student has significantly less opportunity to experience "real world".
