Per The Daring Dufas:
I have to wonder if any parent these days would allow a
six year old on his/her own to travel unaccompanied on public
transportation to another city and walk several blocks to and from the city bus? o_O

We used to send our #2 daughter to Germany - unaccompanied - when she
was five years old.

Not today, that's for sure....
