Balance

Comment:
Great shot. Many Bay Area residents will recognize this as the work of Bill Dan, who has been publicly balancing rocks for a number of years.
More images of his art, as well as links to other rock-balancers world-wide, can be found at //www.rock-on-rock-on.com - and the webmaster of that site (me) would like permission to include this photo on it.
