They can't exactly go in ditches because a tornado in almost any case is much wider than a ditch Ditches are actually recommended for cover if other shelter is not available. This does not guarantee survival, however.
Yes. Contrary to popular belief hills do not hinder tornadoes.
no
It depends how deep, but yes the safest thing to do during tornadoes is to get underground.

They don't exactly skip over ditches. The winds may have some difficulty entering such a small space, the the main safety advantage is by getting so low you do not present as much of a profile to the winds and are shielded from some of the debris. Getting in a ditch is only a last resort.
Ditches are a kind of hole.
Into small separate ditches or estuaries.
Yes, everywhere you go, there are probably reports of tornadoes in the past. Tornadoes have spawned everywhere except Antarctica.

Yes. Contrary to popular belief hills do not hinder tornadoes.

Yes. Contrary to what many believe, hills do not stop tornadoes.
