getting even pickier...
XC time is defined as:
(C) that includes a landing at a point other than the point of departure; and
There is an "except as provided" blah blah blah...
followed by: ... for the purposes of meeting aeronautical experience for... ppl, com, inst...
(B) That includes a point of landing that was at least 50 nm from the original point of departure; and
Now for my picky part... you don't actually have to land someplace other than your point of departure; you just need to go to a point of landing, ie and airport (not just some landmark), if you are logging it as XC time towards the ppl, com, or inst.
(my interpretation, (and some others))
