Way back when (1967: sophomore year is HS) we used to save up our hard-earned dough and reload all the Arisaka (Type 99 7.7mm) brass we could get our hands on, compile our boxes and bags of 22lr, a couple boxes of .38 Specials (just not many 9mm's available to us, back then: I had an acquaintance whose Dad brought back a Luger & a P-38 but we only got to shoot those once), a box of 30/30, maybe and go shootin'!
Nobody thought it unusual to see a carload of teenagers filling a trunk with rifles, boxes, cans and bottles and heading out into "the country". That's where you went: out to somebody's cousin's farm where, with permission, we used to make a lot of noise and have a lot of fun.
Unsupervised, of course. What was the point if you were responsible?
Now-a-days, just IMAGINE! Probably make the front page of the newspaper...
Cheers!
