How are numbers assigned for DE?

[George3]

NASA is the acronym for National Auto Sport Association.  A club that is dedicated to High Performance driving and training, of which Darren and I are both instructors with.  They stage DE's at many of the same tracks as PCA clubs.  Advanced NASA events also include racing.  Our local chapter is called the Northeast Region.

It's a great organization that is similar in style to PCA, excepting that it allows all marques, not just Porsche's to participate.  Personally, I feel you would be better served with PCA, because of most of the PCA Instructor's skill levels and familarity with your car.
