Even as late as the 80's every P'up in the parking lot had a gun , usually in a window rack , from the first weekend after school started until the end of February . Everybody hunted or worked something related to farming ..... Knives were understood to be a no-no but that was only applied to things like automatic openers and butterfly types everything else was working tools , teachers often asked for mine ..... Cops would drive through the known party pits to inventory cars and say things like "the unescorted minors will be home or camped out by 11 , right . " Never a word about the kid puking in the weeds . Same town today , they look sideways at you if you have kids and a 6 pack in the same car . So far the local/regional LEOs are still cool about guns at least outside of 1 county . A lot of laws have changed in the last 10 yr though , and not for the better at least not for kids or parents ......
