Zion Plecker lightly held his putter, judging the distance between his ball and the hole and taking careful mental measurements of slope, wind speed and the lay of the rug inside the Jefferson Madison Regional Library.

Then he gave it a whack, sending the ball careening through the cold rolled steel bookend that acted as a cup.

“Aw, man!” he said.

Zion, who is 7½ at an age when those extra six months make a big difference, was hitting his stride at the Central Library’s mini-golf night, when the library becomes a 9-hole temporary Putt-Putt golf course.
