I got to see that last events at the old Tucson Dragway. That track reminded me so much of the old SoCal tracks. I moved to Arizona in 1981 & Tucson was pretty much it as far as drag racing went. Did get to see a few AHRA races until the track closed. I also heard a wild story that drug runners were landing planes on the track at night to bring in a load of whatever. Don't know if that is true or not. I do like the "new" Tucson Drags, track is a lot better & it has become the sportsmen track in Arizona. Lotta good races there.
