636 Athens Neighborhoods; Digital Nomads; Venice Lagoon

Some people are figuring out how to work from home, while making that home overseas. An American "digital nomad" tells us how he's made it work, from his home base in the Republic of Georgia.

And we wade into the issues behind the flooding that often threatens Venice.
