Wouldn't ever have done that, as she would have driven and I was terrified the time I let her drive in a town. Feared she was going to ram cars.
I let her drive on back roads with no traffic.
Taking a shortcut on the MHS loop I took a wrong turn ( no signposts ) and ended up in middle of nowhere village. Had to go back and road so bad she started crying.
Worst road I drove in LOS was forest road, and took 3 hours in 1st and second gear. I enjoyed it, but not sure if she did.
On the way to it we asked some locals for directions and they told us not to use it as too bad, but quite a few houses built along it.
