You're at Dreamforce, near Moscone West, and in need of a cab to Fisherman's Wharf (for souvenirs
and dinner, of course). You flag one down, hop in, tell the cabbie your destination and BAM
! The ceiling lights up, and you realize: THIS IS THE DREAMFORCE CASH CAB!
You spend the next two-and-a-half miles answering SFDC-related trivia questions, racking up cash to spend on beer and chachkies.
Salesforce could air recordings of surprised participants answering trivia throughout the conference... attendees could win cash and learn more about SFDC in the process... everyone has a good time... I call it a "win win".
Who's with me??
