Yes. There were (are) several people that worked at the schools that have a Texas CHL and secure their weapon in their car during the day. Most of the LEO around here know who carries legally especially when it comes to school personnel/administration. There are several small out-lying small districts in and around Kerr County. Not all of them can expect quick (enough) response on a regular basis in case of emergency.
State CHL exempts you from the law, don't we all know that???? The OP does not have a CHL from Texas.
