Lost whales might have returned to sea unseen

Since that last news I could find on the whales was two days ago when scientists and onlookers lost track of the whales, it looks like the two finally made it back to sea. After all the coverage of these lost whales it almost seems disappointing that there was no fanfare event of them crossing into the ocean.

Rescuers open fire, with water, on lost whales

Does anyone else think that this situation with the whales in the Sacramento River is getting a little ridiculous? I find it hard to believe that there's nothing better that can be done than what's been tried already. Now they've found that using a fire hose seems to help drive them, but they're not going to try it again until Tuesday.

The rescuers decided to try the fire hose after the lost whales resisted attempts to move them down river through banging pipes, a flotilla of boats and the recordings of fellow humpbacks and killer orcas.

The two whales apparently took a wrong turn when they entered San Francisco Bay and traveled 90 miles inland up the Sacramento River. They turned around at the Port of Sacramento and were making progress Monday when they reached the Rio Vista Bridge and began swimming in circles.

I understand that they're wild animals so it's tough to figure out how much to interfere, but it's so sad to read about the whales' injuries and skin problems due to the fresh water.
