I'm back from Japan almost 3 weeks now and there are some things I sorely miss.

First, the train system.

You can get damn near anywhere in Japan using trains. Get yourself an IC card and you can tap on/tap off trains nationwide. (Get one on your phone and you can transfer funds directly from your bank account and use it to pay for purchases, too. Bye, bye foreign ATM's).

Japan is roughly the size of California. Could you imagine California with a train system this elaborate!
