Bull’s-Eye!
July 21st, 2022

Today is the final day of Archery at the Olympics.  In this dramatic sport, the archers draw back their bows and launch arrows into the air at about 150 miles an hour, while the rest of us scramble to get out of the way.  Their target is a flat circle 77 yards away (where a yard is 3 feet) ringed with 10 colorful concentric circles.  Of course, the closer to the center you hit, the more points you get: the gold circle in the middle fetches 10 points, the next circle around it scores 9, and so on until the white ring on the edge, worth just 1 point.  The better your aim, the faster those numbers add up.
