An opportunity to play hi-tech hide-and-seek is coming to Lake Red Rock later this month. Geocaching, which involves using global positioning systems to search for hidden “caches”, will be hosted by the Park Rangers at Lake Red Rock. Participants can bring their own GPS unit or borrow one from the rangers. There is no charge to participate and reservations are not necessary. The geocaching program at Lake Red Rock will be Saturday, November 21st at 10:00 a.m. at the Visitor Center.
