ethnicity: 100% African-American, or as 100% as any of us get.

New Orleans. Something about those people and that city just calls to me.
3) What's one language you wish you knew fluently?
Several, starting with Spanish, Arabic, and Mandarin. Swahili would be useful.
4) If you could move anywhere in the world and be guaranteed a job, etc., where would you go?

I'll have to think about that. Dunno.
