I-35 Speedway IS RACING tonight, September 1, 2018! Mother Nature continues to bless I-35 Speedway, after a week of on and off rain in this drought-stricken area, she is providing great weather to dry out the moisture she provided us. Gates open at 4:30, hot laps at 6:15, racing at 7 P.M. Tickets are $12 for adults, $10 for seniors and military, and 18 years old and younger are FREE. See everyone tonight for some great racing action!
