Christopher,

ANA held its annual convention in Dallas in 2005  http://www.visitnepal.com/ana2005/homepage.html.  Look up Friends of Nepal's director in Dallas.  Also, contact Nepalese Society Texas http://www.nepalesesociety.org/front/index.php

I'm not sure if they're still operating, but there is/was a weekly Nepali radio show in Dallas on 104.9 FM: http://www.everestmediausa.com/

Thanks for what you're doing.
