Carry in your car? Heck, in most places your G.I. Joe doll has to be disarmed! I'm not kidding.
But you can carry a firearm in Texas schools with proper permission.
Interestingly, it was not against the law to carry a firearm at Virginia Tech. It was a SCHOOL rule and subjected the offender to disciplinary action (if a student, staff, or faculty). Visitors could go wild.
Again, in Texas, one may carry a concealed firearm in the state capitol or even the governor's office (our governor has a CHL). This may not last, though. A couple of weeks ago, some person left his representative's office, walked out to the capitol's front porch, pulled out his hog-leg, fired a few rounds in the air, and yelled out "Yee-Haw, Sani-Flush!"n fact the legislature got so pissed at some cities posting various things like libraries and parks, that a new law prohibits any government entity from disallowing firearms on any property owned or controlled by any branch of government. This includes libraries, parks, city hall, waste treatment plants, city owned busses, convention centers, anything. Of course there are obvious exceptions, like jails and courts.
Now some liberal representative (yes, we do have a few - we keep them around to show school children) is making noises about metal detectors and strip searches for capitol visitors. I sent him an email along the lines that if he was afraid to be in his office, he could resign, go back home, and sell earth shoes for a living.
I haven't gotten a response yet. I'm sure he figures he's safer in his capitol office - even with CHL weapons around - than he is back home in his ghetto.
