2020 Buttonwillow Spectator Tickets and Will Call
As part of an overall effort to expedite driver check-in, we have eliminated the use of handwritten "Will Call" lists, although purchasing your tickets via Eventbrite below serves the same purpose. A few things will help us help you.
  •  Walking up to the Registration check-in desk WITH a printed copy OR your phone open to your BAR CODE is the quickest and easiest way to get you into the event. 
  • If you are not sure what the bullet above means, CHECK YOUR EMAIL! You should have received one from Eventbrite with the PDF barcode each time you purchase tickets. That is what we need to see AS YOU APPROACH the check-in area.
  • If you know the name of your MECHANIC or other attendee(s), please include their name(s) on their tickets. Adding their email address(es) will even send a copy directly to them. (NOTE: Mechanic passes are NOT automatically included with a driver’s race entry, nor can they be purchased with the entry through Only thru Eventbrite.)
  • If you don't know the name of your MECHANIC or other attendee(s), that's ok too – but you must send them a copy of their ticket. Even a screenshot of the barcode via text will work!
  • We can usually check someone in manually with a name look-up, but verification could delay their entry thru the gate -- so please make every attempt to provide them with their BAR CODED ticket.

Parents, Guardians and Team Principles

If you need to check in a driver for age or language reasons, you can still purchase a ticket for yourself below ahead of time – or you can purchase it at Driver Registration. Purchasing passes ahead of time below helps expedite check-in and keeps the lines moving faster.
