Just as a reminder, the Independence Day holiday brings with it a suite of service changes. Four of the five local major transit services (SEPTA, PATCO, NJT, Amtrak) will be operating on Sunday or Major Holiday schedules tomorrow, July 4th. DART First State will be shut down entirely except for Routes 201-208 and Route 305.
Extra SEPTA Regional Rail trains will leave Center City after the fireworks. As July 4th is a Friday, the Subway and El will be running train service all night.
My Independence Day plans involve changing from the Capitol Limited to the Empire Builder in Chicago, and maybe catching some of the fireworks from trackside at St. Paul Union Depot. I hope your holiday is, Arthur willing, as fun as mine will be. Happy Fourth!
