One thing I forgot to add yesterday--
The guy I shared the panel with at the SNU conference is an anthropologist researching the Latinization of the South. He is also, like myself, a fanatical fan of Mexican regional and borderlands music, and has written articles describing fieldwork among the new Mexican migrants in the South and also studying the lyrical politics of Los Tigres del Norte.
It figures I had to come all the way to Seoul, Korea to find another gringo with the same interests and with a well developed understanding of, and good taste in, Mexican music.
There is an old saying: The fewer donkeys, the more corncobs.
