This is Curitiba:

the city I live in.

Youtube.

Very nice, Casper. I'll visit Curitiba someday.

I remember, I've been there once...with Google Earth!

Very impressive! it's a megapole actually, more than 2 million inhibitants!
But they seem to take care of the environment there, and make it more human despite size of the city. Very modern and efficient urban transports.

I'll have a tour there, when retired in Brazil, how many hours from Fortaleza?

This is an impressive city

Agree, impressive city Casper
