The Ironbound neighborhood of Newark is technically in the United States. But visit when the Major League Soccer Red Bulls are playing and you'll feel teleported to the Continent. The area has long been a stronghold for Italian, Polish, Spanish, and Portuguese immigrants. Add the Euro transplants who train in from Manhattan and you've got a melting pot of 25,000 drum-banging, "Olé"-chanting maniacs. It's a short walk to nearby taverns, where you can down cerveza with garlic shrimp and barbecued chicken. Then hop in your car and drive back to America.
Getting there: From Manhattan, take the PATH train to Harrison station, four blocks away from the stadium. During the regular season from March through October, Red Bulls tickets start at $25.
