What place is HTX in the US?

Excuse me, could you possibly clarify for me where exactly HTX is located within the United States? I'm trying to get a better understanding of its geographical position and how it fits into the broader context of the country. Is it situated in a major city, or perhaps a more rural area? And if so, which state or region is it part of? I'm eager to learn more about this location and how it contributes to the country's economic and cultural landscape.
