Big Sky Country (not Montana)

Back in March, I took a trip down to Texas to visit a dear framily member. While I have never been to Montana, I couldn't help but wonder if the 'big sky country' nickname applies to other places, like Texas. My hunch is that it totally does. As much as the cities are being built up in Texas, if you look up, the sky just seems to keep going.

My feeble attempts to capture the sky in image are below.
