[DeTomaso] Pantera Aerodynamics

[Mad Dog Antenucci]

Someone once asked John Wayne how did he learn to drive so fast....okay the question was how did you learn to walk the way you do....his answer:
   
  "By putting one foot in front of the other"
   
  Thats how you get it done people. Stop trying to put lipstick on a pig...Get in the car and go!

I like that...I even understood most of it. Real numbers from one area wouldn't mean much to us, but
relative number form several different points would be interesting. Thanks.
