There are not enough known fact to give you a 100% accurate answer on this one unfortunately; the fact that cases haven’t been prosecuted on this issue (win, lose, or otherwise) means we don’t have much judicial interpretation to fall back on. The reason it is a difficult question to answer is because there are potentially places that are off limits under 46.03 and 46.035 of the Texas Penal Code (potentially the beer gardens, which may have a 51% sign, or any professional rodeo/sporting events). A 30.06 sign posted on governmental property is legal if it is on property that is otherwise prohibited under the law; but the question is, does having some property off limits invalidate the entirety of the property? If there were no posted 30.06 sign, it would be an easy question to answer; don’t carry past any 51% signs, or into any professional sporting events. However, the 30.06 sign issue is one we don’t know just yet; the attorney question is considering a very similar issue right now, so hopefully by the time the Fair rolls around next year we will have a better answer for you.
