A Slice of Paradise in SF?

Now here's a postcard perfect shot that I took today at the Golden Gate National Recreation Area in the city of San Francisco.

Irony is, though, if you stood on that beach for an entire day, you most likely wouldn't survive.

The reasons:

1. Rising tide coming in would take you out to sea.
2. Temperture of the water is probably in the 60s or less, a body numbing, if not killing, experience if you were submerged in it for more than a few minutes.
3. Riptides--you can't see 'em, but they're there, and if you got swept up by a wave, the rest of the work to put you to your demise would be done by a swift undersea current.
