Note: France and Italy have adopted a system that is basically a legal
way to extort money from foreigners. Buying a ticket at the station is
not enough: you also have to "validate" it in a small red machine.
If you forget to validate it, you may get fined, and the fine can be as much
as the price of the ticket. Italy and France have a reputation for inventing
the silliest bureaucratic rules and this one is also very smart, as almost
no foreign tourist will think of sticking a perfectly valid ticket into
a small red machine. All instructions, needless to say, are written only
in Italian or French. Please help boycott the national railways of France
and Italy: travel by bus.
