We saw this example of urban geometry in downtown San Francisco CA recently so we took a photo (with our trusty Coolpix.)
This sign is not on the wall of the employee lounge at the World’s Laziest Journalist’s home office (we wish it were). It is posted on the wall where tours at the Nethercutt Museum begin and that gives us a legitimate reason for calling Jalopnik’s photo editor’s attention to this post. When Jalopnik ran an item linking to one of our posts about the 2009 SummerNats in Canberra, they sent several hundred new readers our way. Will lightening strike twice?
