Europe for travel within the Schengen Zone has at least been moving back in the right direction of no papers required for travel. Meanwhile, in North America and the Caribbean it was perfectly normal to be able to travel around with no passport up until just a decade or so ago.
I remember being able to go to visit Canada from the USA with nothing more than someone asking if you if you are a US citizen.
That freedom to travel is yet another right that was thrown out the door because of 9/11 via the "Western Hemisphere Travel Initiative" [1] which would be more aptly named the "Western Hemisphere Restriction of Travel Initiative"
Sad.
