Allentown is the county seat of Lehigh County and the 3rd most populated city in Pennsylvania. Allentown is also one of the fastest growing cities in all of Pennsylvania. The area’s economy primarily consists of service industries with some manufacturing. However, there has also been significant growth in the healthcare, transportation and warehousing industries. Easton is the county seat of Northampton County, bordering New Jersey. Just north of The Valley is Carbon County. The county seat of Carbon is Jim Thorpe, which can be easily accessed from Rt. 209 and Rt. 903. The town has been called the “Switzerland of America” by the Swiss Tourist Board due to the scenery, mountainous location, and architecture.
