HB2127 was signed by the Governor on 6-17-11.
It was specifically enrolled to prevent Fort Worth from prohibiting the discharge of weapons on tracts of more than 100 acres in its extraterritorial jurisdiction or areas annexed on or before September 1, 1981. It looks like they worded the bill in such a way that it only applies to Ft Worth.
