I was born and raise in Williamsport and it will always be home. I made lifelong friends there and it has a lot to offer.
If heading there in the summer, you have to know williamsport is Little League Central. Everythign revolves around LL and the LL World Series comes in late August. The town, as well as South Williamsport, will be crowded and traffic will be crazy. But, its all worth it.
During the rest of the year its pretty calm and scenic. The mountains are gorgeous and Williamsport definatly experiences every season.
Its a wonderful, homey town and great oplace to go.
