The San Antonio Raceway website says admission on Friday is $10. Not sure about the cost to run Friday. Camping is free. Saturday, $20 admission and $20 for one tech card. If you run in both an index class and the bracket class, that would require two tech cards. You are allowed to run in both classes, but not on a single tech card (track rules). First round bracket losers can buy back in. Reminder to bracket racers: no electronics at this race.
