Warped Tour's spokesperson, Kristine Ashton over at MSO, sent me this press release via email today:

Organizers of the VANS WARPED TOUR want fans to beware that counterfeit tickets have been sold in the parking lots of some Southern California shows. Counterfeit tickets will not be honored at the venues.

If fans haven't purchased tickets in advance for the shows, they should do so at the box office on the day of the event.

Buyer beware.
