Southern California - no place to drag race in the birthplace of drag racing

I would make the argument that drag racing now is AS popular or MORE popular than it ever has been. Maybe in a different form than you’re used to (no prep, back of track, street etc) but the popularity is there. The tracks that embrace change will survive.
My question is this, if it's so popular then why do they keep closing tracks down? There used to be 4 verily close to me and now there's only one. The one that's left is in Madison Illinois and I think that they finally phased out Friday night madness unless it's been brought back in the last couple of years. The newer generation is into electronics. They canceled a car show in my town due to the fact that they couldn't get any judges for the show.
