Quite a few adventurous Dolphin Club members swim at China Beach!
Here’s one way to take matters into your own hands when the federal government is shut down, as one frequent swimmer at SF’s China Beach saw the beach was closed for the shutdown, so he simply GoFundMe’d up the money to reopen it. buff.ly/VXuPkF7

Once abundant in California waters, the sunflower sea star was nearly wiped out by sea star wasting disease. The cause wasn't clear at first, but one culprit has been identified—a bacterium named Vibrio pectenicida. This finding may help scientists understand and control this disease.

I'll be 55 on Saturday. It's literally my job to explore San Francisco and pass on my finds to others.
And up until last month, I had never visited one of the two most renown landmarks in the city.
I finally checked out Alcatraz. Was it worth the wait?
