That's what I was thinking! Who goes camping for 3 weeks, presumably in a tent? With a 2 year old? Even in the best of circumstances? Not me!
LE must be worried if they're using a plane.
Not me either, but I’m distantly acquainted with a few people who do this with toddlers. It’s more of a hippie or off-the-grid lifestyle thing - they like the great outdoors and have the philosophy that “kids join our lives, we don’t join theirs.” If that’s the philosophy here (and we don’t know, to my knowledge), it ceased when Jill didn’t return for her son on the weekend.
