Gun control groups are also leading businesses and the media to believe that a 30.06 sign is the only way to prohibit the lawful open carry of long guns on private property.
This article from
The Wall Street Journal states:
Current Texas law doesn't contain any prohibitions on publicly carrying long guns unless they are displayed in a manner "calculated to alarm," or brought into an establishment displaying a "30.06" sign, a reference to the statute that allows Texas private-property owners to ban firearms on their premises.
In reality, a 30.06 sign is not required to prohibit the carrying of long guns on private property and, in fact,
does not prohibit the carrying of long guns on private property. Unfortunately, many business owners now believe that a 30.06 sign is the only way to keep out open carry activists.
