your local agricultural extension co-op (in Texas they call them Agrilife extension offices)
just do a search with your county name and "AgriLife Extension"
so since I am in Lampasas county.. I would google
"Lampasas county AgriLife Extension"
For San Antonio.. you would be in Bexar county... here;s their contact info: http://bexar-tx.tamu.edu/contact-us/
you can actually find a lot of info on things in your area...
for instance ...they are offering a beekeeping program on the 18th... http://today.agrilife.org/2012/04/23/bexar-beekeeping/
Thanks for info!!I sent a email so hopefully I get a reply soon
