Don't know whether this is current...

It looks like a fairly ancient site from my knowledge of Houston girls.  Sunset Thomas is up and being shown as based out of Corpus.  She has been based out of Reno for Years now.

My guess is it hasn't been updated in 3-4 years.

The last I heard of her availability was 2002 in Houston at a spa. She hasn't appear anywhere else in Houston.
