I'm pretty sure Greg's right, they let you run 1/4 mile and the big dogs run the 1/8. I have been since the new owners took over and I ran the 1/4 (49.00's back in the day). I didn't know it; and showed up the first night they opened since they re-did the whole track and I spun the whole 1/8. Nostalgia drags are on the following Saturday and the invite card says 1/4.
