I grew up in what was, at the time, rural Texas. (now just another part of Houston I believe, lol) If you went out to my high school's parking lot you'd find lots of guns! Most, if not all, the trucks had gun racks and there were guns on the racks! Even the narc dogs ignored them (but they didn't ignore Jack Daniels bottles, pot seeds and hand guns)
But that was a different time.
I am a senior in high school and 90% of the time I’m in school, I have a hunting rifle in the trunk. If you went through the vehicles at my school you will find many more. I don’t see the big deal in it honestly.
