my 3 boys are all over 21...and from the time they could heft a firearm I have pix of them doing the boy thing...handling guns. that and videos of them shooting at a ridiculous young age. and I only say ridiculous because that is what it is considered in the north east location in which I (still) live.
In REAL America it would be perfectly normal. I plan on living there some day soon.
I’d wait until the traitor is out of office before moving here unless you’d be an illegal alien then he’ll welcome you with open arms, entitlementsand free healthcare as long as you vote for him...: )
