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

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.
Land values and noise.
I DONT think those are the problems at Irwindale.
The money going in the toilet for the roundy round is killing the dragstrip AGAIN.
