Hotel rooms are my staple diet. But going all the way to San Francisco to sit in a hotel room, watching American rap-stars deny beating up American pop-stars would be a damn shame. So I tapped up my colleagues. Challenge me to do stuff, I asked them, I want to see the real city. So they did. And this is the result. The collected works of my San Francisco challenges, as set by my US colleagues. (PS, if you all don't check out the brilliant www.benjigraphics.co.uk then your Mothers ought to wish you'd never been born)
