When I was a boy, every truck you saw in Texas (even in urban areas) seemed to have a gun rack in the back window with two or three different long guns proudly displayed on it. A rifle or two and a shotgun were not at all uncommon to see inside vehicle windows, but that definitely is now quite rare. While not illegal, people are more conscious of concealing their firearms in vehicles due to theft and urbanization (people aren't as used to seeing firearms in plain sight these days). That said, just because you can't see them doesn't mean...
