Read about it last night after reading your post. I am in Tucson. I used to go up to Chandler. My mom lives 13 minutes from the track.
I did not like all the bad attitudes up there.
It is a much faster track than tucson as DA is 2000 feet lower and I heard a smidgen down hill vs uphill in tucson.
But any track that closes is bad.
So we have gone from 3 down to 1 track. There used to be another near Sun City. North west of Phoenix.
Well that will be good business for Tucson dragway.
It will become busier and not close itself.
