ummmm, while that sucks and all, Vegas will never close and its no 500 miles from So-Cal.... plus its open almost all the time. its ~350-ish miles from San Diego and ~280 from Santa Clarita.
Speedworld in Whitman AZ..... 400-ish miles from Santa Clarita, about the northernmost place in So-Cal.
Firebird in Chandler, AZ...... 425-ish miles from Santa Clarita, again, northernmost place in So-Cal.
you have options if you are making the area 500 mile radius from anywhere in So-Cal. they just arent really close to you anymore.




Barona isn't an option for me only because my current car really only wakes up after the 1/8 mile mark (expecting something like a 13.8 @ 110 in the 1/4).
1/8 mile tracks are a waste of gas for me! 
I don't know, maybe there's a gas station up there with E85. But then there's the issue of breaking like someone mentioned...if I break at Fontana, or Irwindale...AAA will cover my tow (100 miles). But if I break in Bakersfield or Vegas, I'm in serious trouble.
