“Stay away from the Spanish Quarter. It’s dangerous!” The young man sitting in front of me on Amtrak’s Northeastern Corridor train from Philadelphia to Newark International Airport advises. Rick and I fly out of Newark on a two-stop flight ending in Naples, Italy, in a few hours. We’ll join a group to tour the city and explore the Amalfi Coast for ten days. These accusations about Napoli pique my curiosity. I’m eager to see it in action, especially to visit the “dangerous” Quartieri Spagnoli, the city’s Spanish Quarter.
