San Justo, Argentina

Living in San Justo is no picnic. This town in Argentina's Santa Fe province has a population of 105,274, but it's also home to the deadliest tornado in South American history. In 1973, an F5 monster ripped through the town, killing 63 people and leaving over 2,000 homeless. Rescue efforts were hampered by widespread power outages and communications blackouts. Even today, bureaucracy is a persistent headache for locals.

This is not the place for the faint of heart. The threat of extreme weather and the challenges of getting things done make San Justo a tough sell, even for the most adventurous expats.
