I am NOT an expert.

I have built (a few) and set up race cars for almost 30 years. I have made more laps in a water truck than
some racers have made in a race car. Here are my observations:

Building and tuning a race track is as hard or harder than building and tuning a race car.

The tracks that have a consistently good racing surface are on par with the performance of Donny
Schatz and his crew chief (last few years) and the Steve and Karl Kinser combination.

Getting the correct mixture of dirts, organic matter and chemicals takes a wizard.

Guessing the temperature, humidity, amount of moisture in the track, if, when and how much of it will
come to the surface, how many cars will show up and how they will affect the track surface... well you
get the idea!

The folks that get it right deserve a big thumbs up. Have a bit of compassion when they miss the "set up"
a little. IT AIN'T EASY!
