I LIVE on a bad road. Almost a mile of dirt road with ruts, holes etc. All the constant shaking has rooted out the weeak or loose fasteners. I am not the only one who uses this road so I used to see a bolt or some such hardware on the road and think "oh look, someone lost a bolt,"
Then I get home and discover it was mine. Of course when I go to look for it I can't find it.
So now I am in the habit of stopping and picking it up when I first see it. Sometimes I need it, sometimes not. I even do this when I'm in the desert. If it's useable I keep it, if not, into the trash bag it goes. Never hurts to pick up a potential tire biter.
I now have a good selection of hardware if I am in the boonies and discover something has jumped ship.
All the advice here is good. Air down or not, go slow or fast on washboards, etc.
