While my wife was at a conference in Phoenix, I took the light rail (and walked a mile and a half) to go to the zoo. The lines to get in were very long, but I got in quickly by pulling out the phone and buying the ticket online. It was $25, and the ticket barcode came up right away. I bypassed the line and had the phone scanned in less than a minute. Here are some pictures I took.
