Pictures like this are among the best responses to the "good old days" crowd. Just look at the condition of the houses and other buildings pictured in these photos and compare with today (today they've just about all been renovated and are worth plenty). In the photos even the commercial buildings in Chinatown and elsewhere look like wrecks whereas today they are well-maintained.

And the pics take a little of the nostalgia out of ideas about 60's Haight-Ashbury too.

They even suggest reason for hope for cities that are currently in the condition San Francisco was then--you know the ones (they get regularly trashed here).
