Well I have Played with Dave in the Salt Box a couple of Times now... I am
going to take a stab at a few of Dave's Laws of Racing....

1. Bring Bud Light and ICE...

2.  Commitment... ( be Serious in the effort... It' more fun to set records
then go Fairly Fast)

3.  25 mph over a record is a better planning goal then 2 mph and it gives
you alot more margin for error and bad air days...

4.  Laugh alot....

5.  Think More then you Laugh....

6.  Last Tune up.... of the Day.... Make sure you put the Bud Light on
ICE...

7.  Bring a Water Cooled Check Book.

8.  Bring Spares.... ( bud Light.... Three Page check book... if it fits in
your back pocket it ain't got enough water cooling...)( check with Wendover
water department for Secondary cooling for the check book)

9.  These are world Records... and they are all Easy... Just bring Better
equipment then the last guy and be smarter...

10.  Don't Second Guess the Tuner... ( no matter how bad it feels between
those last two sets of Orange panels...)

Keith ( This ain't a Bud Light Marathon... but a fella has to keep it all in
Perspective )( dancing Girls might Help...)
