A thriving industrial center in the 19th century, its struggles in the "post-industrial" 20th century became the lyrics of a famous song by Billy Joel named after "Allentown," its biggest city. Lehigh Valley has begun to turn itself around with some success through tourism with several outlying ski resorts, an amusement park, Minor League Baseball team, a casino, concerts and cultural festivals year round. It also has become an increasingly popular bedroom community for those with professional jobs in New York City and Philadelphia. The Lehigh Valley is 730 square miles.

Allentown, Bethlehem, and Easton all experience crime. Much of the crime is gang-related, so try to stay out of poor neighborhoods and housing projects. The main gangs are 18th Street, Black Dragons, Bloods, Crips, Latin Kings, Los Solidos, Mexican Mafia, GGU, and MS-13 in the area. They are the most violent gangs in the country.
Graffiti is also common, especially in Allentown and also on Bethlehem's South Side. Theft is an issue, so be sure to lock cars and stay out of certain areas at night. Prostitution and street drag racing are also issues in Lehigh Valley. Avoid walking alone late at night or on unlit streets or wandering too far off the main streets. If homeless approach you for change, just keep walking if you do not want to give anything. Pickpocketing is not a large problem, but still do not flash around your money.
