More "Wall Stuff" for Wall Wednesdays" (Good Stuff!)  

Actually, it came down slowly thru the 70's, with better cars, tires, and engines, to a 13.3 Jim Hendrickson Turkey Derby track record in 1974. It than dropped to 12.0 by Tony Siscone in the mid 80's. It has really leveled off since then.  The only difference between the mid 80's and say 2020, is a dozen guys can run around the 12.0-12.2 area, where back than, only a couple could. Turkey Derby times were always faster due to the cooler weather.   Turkey Derby was always a challenge, you would go out early morning practice, cold temperatures, and after you got good tire heat, you could run three tenths faster than you could all year. It was a challenge you looked forward to all year.  It was kind of bragging rights if you were the fastest.

Wall, like most tracks, would slow down three to four tenths in the summer due to the heavy air on the engines and the heat of the tires (too hot).
