Another fun time was had with seven friends sailing & scuba diving in the Caribbean on a catamaran called The Moonshadow. With a Christian church group tour of Greece, Jayne & Rich followed the Footsteps of Paul the Apostle. A visit with special friends in Washington followed by an Alaskan cruise was a favorite recent trip.
