MOO MOO
I'm not suspicious of the neighbors, I'm not even suggesting that Michelle is in the canal.
I assume that if BabyD & PapaD act consistently like they appear to on news video, the neighbors might believe the family "can be difficult" and would not want to annoy them. The guide ropes the divers stayed within were there for a reason and I don't know what that reason is.
If I had a neighbor who I thought MIGHT BE shady, I wouldn't want to annoy them, and extending the search onto my property might annoy them.
If a body is found on one's own property, one might have a problem explaining how it got there, PARTICULARLY IF ONE HAS CLAIMED THAT THEY LAST SAW THE MISSING PERSON DRIVING AWAY.
All of us have a tendency to think others think like we do, because that is our only frame of reference. I'm thinking that thinking a little out or our own boxes might help us stumble onto some helpful information.
