Atlanta's another metro system where people have said I was crazy to mix
it with the locals. It's a very deep seated prejudice.

Yes, it's straightforward racial prejudice with MARTA. That could also
apply to some other public transit systems that serve airports.

It's a prejudice against muggers, which Hollywood (and others) portray
as infesting metro systems. The ethnicity of the muggers will depend on
which country, as well as which city.
