This topic has gone round and round, and the general consensus on this board is that MX is a great value but very expensive, and those who are not familiar with it or interested or curious enough to see it as a great value, and willing to pony up the big bucks and totally commit yourself before you ever get started should just stay away from it, and thats what people do. That pretty much limits your "growth of the sport" potential to the kids of current racers or friends of current racers. And "growth of the sport" should not be confused with increasing attendance by capturing a larger portion of the existing racers at a given location. Thats called "business competition for market share". Adding racers to the sport, who were not previously racing is "growth" of the sport. Increasing your market share improves profitability in real time for you, but those other places who lost market share to you experience the decline.
Growing the sport is a long term investment, hard work, and not profitable in the short term, nor is there guarentee it will bear fruit in the long run. There is a huge untapped potential market out there of anybody who owns a bike or quad. It remains untapped because, even though they may be interested in running a track, they do not see laying out $60 or $70 to appease their curiosity as the same "great value" as those who race regularly. Some seemed shocked that a first time racer is not thrilled about being required to help fund an awards banquet he has absoluetly no interest in, in order to be permitted to make his test run at a local race.
Then we have the guys who enjoy racing only a couple times a year, and have no interest in series, or points, or year end awards, or awards banquets. They mostly do outlaw tracks, because sanctioned would rather send them away than allow them to race without funding the awards banquet. You used to see a lot of these guys at fair races when it was affordable. Now they can count on spending $65 for their once a year 8 minutes on the track, so neither they, nor their once a year buddies who came to watch or race with them attend any more.
So all this talk about cost and value by committed riders is useless as it pertains to the non-racing rider. He will not see it that way unless he falls in love with the sport first. He is not being swayed to commit his money and his time to motocross because he is reading the Pitracer clique promising that if he lays out his money now, he will see the great value later. If you want his money, you are going to have to get him on the track, and loving it first. You're not going to convince him by posting on Pitracer. If we are unwilling to find a way to do that, then we should be content with whatever "growth" of new racers that Smith Rd and other outlaw tracks create, and let the existing promoters keep competing for them instead of creating new racers of their own. If your specialty is catering to serious and committed racers for the season, and the year end festivities, that is fine for that group of people, and it may increase your share of existing riders, but it will not result in the growth of the sport you are looking for.
