This makes all of the land adjoining a U.S. UU. See Texas Agriculture Code §§ 143, 101 — 143, 108.There are 22 counties that are legislatively prevented from having closed fields for livestock. A county is open country if voters haven't voted to do so in the short term through a local stock option election.
Texas is an open country state, but counties can hold elections to become closed country and require that livestock be fenced. Many Texas counties were closed in the early 20th century. Johnson County is currently a closed county for certain livestock animals. We have evidence that other counties have enacted stock exchange laws for part of the county, but not for the entire county.
These counties have sent me a letter stating that, as of the date of the letter, they are unaware that no stock laws have been passed in their county.
