PETERSBURG (AP) — Bart and Rhonda Leinberger had an unexpected but welcome visitor at Alpaca Days, held over a late-September weekend at their farm near Petersburg.

It turns out that Star Attraction was, indeed, a star attraction.

The Leinbergers knew one of their alpacas, Heidi, was within days of giving birth. They didn't know she would use the occasion of Alpaca Days — a chance for hundreds of visitors to get up close with the quirky but congenial cousins of llamas and for the Leinbergers to highlight products made from alpacas' luxurious fiber — to birth her first cria.
