GRETNA, Neb. (AP) — A geocaching workshop has been scheduled at the Ak-Sar-Ben Aquarium Outdoor Education Center south of Gretna in eastern Nebraska.

In geocaching, people use GPS devices to search for hidden items.

The event is scheduled for 10 a.m. to noon on June 16. After learning the basics, participants will spend time geocaching elsewhere in Schramm Park State Recreation Area, where the aquarium is situated.

People may bring a lunch. GPS devices will be provided.
