Jup, I was surprised last time I was in downtown Houston which was many years ago, all the signs were also in vietnamese.There is a huge Asian population in the coastal areas here. I say coastal just because that's where I live. Houston isn't 'on' the coast, but close enough to call it that. They have an area they call Chinatown but the little town I live in has a Cambodian community just outside town. There are temples all over. Many Vietnamese, Korean, etc. No one stands out or looks twice. It's just not a thing.
