It has become a bit of a new tradition for me. As I leave New York City from JFK International Airport, I give away whatever leftover subway passes I have. Yesterday as I passed through the gate for the AirTrain I handed my remaining weekly unlimited ride pass to one of the people heading into the city. It often confuses people, and since it is New York, you can see them trying to figure out if it's a scam. But I just tell them how much is left, tell them to enjoy, and head on my way. It's a good way to start out a trip.
