Flights to Philly

In case any of you are thinking of flying to Philadelphia for the Oct. 7 festival, Southwest Airlines still have availability on their $39 each way from PIT-PHL fares...

It's a really easy flight, and then it's about 9 miles to where the festival is taking place (presumably by taxi, unless someone else can find out information about public transit to the Schuylkill river in Fairmount Park?)
