We would walk train tracks as a kid, because a friend of mine found a bent piece of metal he could make a whistle out of. I can't tell you how many nast pieces of metal i put i my mouth trying to make a whistle. lol It never worked.

I am not the best whistler in the world, which you need in raising German Shepherds, lol

And I can barely snap with my left hand. which you need raising kids, lol
