A couple years agog me and the other guys in my firehouse were getting ready to fling some arrows behind the station. They were all sitting at the picnic table with their allen wrenches etc tinkering. I strung my longbow, and waited till they were ready. Of course when the ribbing started, I pulled a $20 bill out of my wallet, and layed it on the table and bet anyone who wanted I'd beat them at 20 yds with one arrow even steven.
Of course one said I'll give ya 10 yds. I smiled, said ok- and buried an arrow dead center. As he nocked up an arrow, I tapped him on the shoulder, and handed him his wrenches.
I told him now take off the sight, string loop, drop away rest, stabilizer, and release THEN you can shoot from 10 yds.
He declined. I smiled, told him to keep his money and buried another arrow in the target.
