Get your hunting clothes on.
Screw on your broadeads.
Climb your treestand, and place a 3d target at 30 yards.
You get ONE arrow.
If you hitBOTH lungs I'll give you $100.
If you MISS the lungs, YOU give ME $1,000.
Would you take that bet? If not, 30 yards is beyond your "effective range".
I love that analogy, and wouldn't mind making a quick $100.
