(AP) -- Everyone seems to have a suggestion to get two wayward whales lingering in the Sacramento River to swim 70 miles back to the Pacific Ocean. One person suggested towing life-sized replicas of orcas behind the whales to scare the recalcitrant mother humpback and her calf. Another proposed placing a giant magnet downriver, since humpbacks are thought to navigate by an internal compass that can sense magnetic north.
