One of my favorite spots for observing sunset over Mount Tamalpais and the Golden Gate is a vacant lot on upper Euclid Avenue in the Berkeley Hills. I don’t know the real estate history of this lot, but it seems at this point like a small city park with a fence protecting people from the drop that overlooks the view.
I’ve tried the solar bisection of the tree trunk idea at this spot before. The trick, of course, is a matter of timing: there’s only a split second in any given sunset in which the sun will be in the right position.
