From the rocky San Francisco Point that I showed yesterday, there is broad crescent shaped beach that extends most of the way to Cabo Velas, the point to the north that you see across the bay.
I took this photo at low tide just a few minutes after taking yesterday's photo. You can see the slope of the beach is very gentle. At high tide you could wade all the way out to the surf in this photo and still be below your waist. Note that there is even a bitof reflection of the clouds visible in the ocean.
We are showing photos of Chicago this week on our Viva la Voyage travel photo site.
