If you've ever been within a two-block radius of the downtown Greyhound Bus Station, you already know just how interesting this place can be. Operating 24 hours a day, seven days a week, it's where you can always get your people-watching fix. Cultural foreigners and foreigners in the literal sense of the word, bohemian types and people just passing through — you get it all. Best of all, it's not like the airport, where you have to have a ticket to get into the terminal. This is an all-access people-watching mecca.
