Street Chess - San Francisco Style

Back in 1996 I was in San Francisco (on my honeymoon) and I spotted a group of chess players playing in the street. In the end I passed up the chance to play as (a) I was afraid of getting 'hustled' and (b) I was on my honeymoon. In the end I probably shouldn't have been so timid (or considerate) as based on this article, they were probably just a bunch of enthusiasts enjoying the game.
