Redline is pretty good, but it's about an hour east of Dallas in Caddo Mills right off I-30 near Greenville.
North Star in Denton is also good, about an hour north of Dallas off of I-35.
Both are 1/8 mile tracks and both are solid, safe tracks with some rules and lots of decent people (unlike Yello Belly).
I've run into several forum guys at Redline.
North Star Friday nights, Redline Saturday nights for open track nights. Redline does get a lot of slicks cars, and they alternate between letting street tire/drag radial cars run and then slicks cars run, so sometimes you spend a lot of time in the lanes waiting to race. Especially when the cars keep wetting down the track and they have to clean up.
You might be in line behind a rail dragster or a ricer at Redline, you never know, but most nights you can get in lots of races between 6-12. I'm probably going to Redline on Oct 11th.
