I took a trip to New York with someone today and the number of strips of paper and bits of plastic required to run the whole loop were manifold.  This included:

1 Parking slip
2 Train tickets into the city
2 Subway tickets/Metro Cards
2 MTA tickets northbound
2 venue entrance tickets
2 MTA tickets southbound
1 Dinner reservation print out
2 Evening event tickets
2 Train tickets out of the city

16 clumps of atoms of some sort required plus keys, wallet, and notepad.  I’m glad the paperless world of tomorrow has arrived.
