There really are no rush tickets, just lotto or cancellations. So if you don't wanna do the lotto (which is two hours before the show), go to the Ford Center's box office and wait there two hours before the show (so you beat the people who didn't win the lotto). Then you will PROBABLY be first in line, and have a really good chance at getting a cancellation ticket (which is $100).
