The dead horse lives!! 
This topic IMO got way off course from the basic, original point of "how to market midget racing".
Races don't magically happen, folks, and while equipment, format, payout, etc. changes are great and many times very warranted -- NONE of that defines the "midget racing product"
for the fans.
Herein lies the problem, maybe...Let's face it, racing is entertainment but it is also clearly a business on every level. One popular business viewpoint is that of "lean" principles in all aspects of that business. In its purest form, "lean" means
anything that doesn't directly benefit the customer is WASTE.
So, let's try another pragmatic angle --
"If you were in charge, how would YOU market a midget series to the general public?" And, could you do it in 5-sentences or less?
I'll start --
1) Twice a month at one track, possibly two, if the other track was within 50-miles away.
2) Track would be 3/8 or less - on dirt.
3) Switch it up to qualify one week; draw another week; fan draw another week.
4) Create multiple fan & sponsor interaction like "speed challenges" w/prizes; sponsor flagman; fan pace car rides; t-shirt tosses, etc.
5) Develop a streaming broadcast or video medium for fans & sponsors to follow when they can't be there or watch races again.
