I want Texas to do the same darn thing! Good for Utah!
When Texas entered the union, because she was a nation, she retained all her lands. Federal lands in Texas are from modern times and there is not a lot of federal land in Texas
Big Bend was originally a state park(100,000 acres) but Texas gave it to the feds in the 1940s. Big Bend Natl Park was greatly expanded by the feds buying additional lands to make it larger.
Sometime along the way Big Bend was given a UNESCO designation and Texas didn't like that. Then the Rotary Club International started promoting Big Bend as a Peace Park with Mexico, and Texas didn't like that.
Big Bend Ranch came up for sale in the 80s. It was quite large and adjoined Big Bend Natl Park. Texas didn't want the Park Service to buy this ranch, so Texas bought it and it has been a financial liability to Texas Parks and Wildlife ever since.
There is very little federal Land in Texas
