I'd suggest including a city on the other side of the country, California.  Given that it is the 60s there's a lot of stuff happening in California.

San Francisco would be great for hippy stuff, Bruce Lee, Chinatown, Triads, racial/lgbt stuff.  LA would be good too for most of the same reasons as well as Hollywood.  Someone mentioned  Richard Dragon earlier and he'd be a great fit for either or both of those cities.

There's also the West Coast Avengers.

Then in history there was lots of interesting stuff happening there.  Beach Boys, Beatles, Manson, Bruce Lee, Haight Ashbury, Scientology, I believe the Children of God cult was active there at that time too.
