That's a new one!
I used to tell the police when I'd be away from home, up north. Then I talked to a cop who was frequently seen patrolling my neighborhood. He said he never was told about anyone who was away!
Even if you were to comply with this DR item, I can't imagine the logistics that folks like Community Watch would have to go through! I can, though, hear them saying, "What, he's gone away again? Sheesh!"
I let a neighbor know (because they'll pick up my paper and mail - and, now, feed The New Cat) but no one else has a need to know!
