Hi! Have you ever met a Hindu from Louisiana?
Why do you say Louisiana? Don't you know that Hindu is a geographical, cultural, and later religious identifier for people indigenous to South Asia?
Because there is a substantial concentration of South Asian immigrants in the southern US! 
I see. If i get you right, SOuthern US has inhabitants from sub-Himalayan SAARC countries and, for some authorities, adjoining countries to the west and east.
Yes. So working on the assumption that Sikhs have established temples and compounds in Texas, I'd guess Hindus have done so as well in neighboring states - like Louisiana. 
I have seen some of their temples around. I learnt few things about the religion and i know the  fundamental beliefs of Sikhism, articulated in the sacred scripture "Guru Granth Sahib", include constant spiritual meditation of God's name, being guided by the Guru
