I agree, It may be useful in heavy road congestion times, and with certain stations surrounded by walkable cities /towns. Do they still film shows in Stamford, CT? Maybe they can have a Woodbury Commons Shuttle from Peekskill.
Yes, but since they increased the price of City Ticket, it’s only useful during peak trips (or when you get a Weekly). Because, off-peak, the City Ticket is better, since you can use it to/from Penn Station if plans change.
