Anyone from San Antonio, TX?

Good morning:
Anyone here originally, formerly, or presently from San Antonio, TX? I am currently reading a (library) book, "HIDDEN KITCHENS", by Nikki Silva and Davia Nelson, based on their NPR series 'Hidden Kitchens'. Story #3 (chapter 3) is "The Chili Queens of San Antonio". A very interesting insight into the chili stands that used to be found at various plazas, and existed for about 100 years (until the health department stepped in in the early 1930's). In addition to the historical background, there are a couple of recipes, and an essay on Lydia Mendoza, "La Alondra de la Frontera" and an essay on West Commerce Mercado. I know this isn't within the realm of Ranchos genealogy, but thought it was an interesting presentation of past history.
Also - is anyone familiar with a film entitled "Chulas Fronteras" (a documentary by Les Blank and Chris Strachwitz)? (DVD of film available from Arhoolie/ www.arhoolie.com; Arhoolie is a small company in California that specializes in obscure music genres and re-issuing old-time recordings. My favorite is "Pachuco Boogie" - yes, it is a part of my personal collection.)

Natalie Castro Coleman, who occasionally, with little success, researches
Castro, Garcia, Duenas, (and related families) from Hda. Astillero (Valparaiso) and Sain Alto, Zac.

PS - I am very much enjoying reading about everyone's efforts and discoveries. Keep 'em coming.
