SIOUX CITY, Iowa (AP) — Organizers of a long-planned Christian-themed park in Sioux City have dedicated the newly opened green space, thanks to private donations. The Shepherd's Garden has opened with plants, walkways, plaques bearing Bible verses and three crosses, the Sioux City Journal reported (http://bit.ly/1K0TctF ). The group turned down a $140,000 state Vision Iowa grant last year after the Wisconsin-based Freedom From Religion Foundation complained that awarding public money to a project intended for religious worship violated the U.S and Iowa constitutions.
