I have been following this thread with great interest, and here is what I take away from all of this;
1. Midget racing is still very much on the minds of the open wheel community. Rumors of the death of Midget racing have been greatly exagerated.
2. As opposed to days gone by, it seems to me that we are starting to hear a more unified voice regarding the direction that the sport needs to go. I remember a time not too long ago when a thread like this would feature a bunch of opinions, almost none of which had anything in common. I'm sensing a little more unification now.
IMO, there is still a balance that needs to be struck between maintianing our traditional inventory, and finding ways to bring in the new breed of Midget engines that will eventually be our future. The good news is that from reading all of these posts, it seems that we have finally reached the point where the majority of supporters agree that 1950's technology does NOT represent the future of the sport. Making the transition will not be a cake walk, but it's really not going to be all that hard either. The hardest part will simply be to finally make the decision to get started.
As I said before, we can take Midget racing from where it is now - an increasingly insignificant, specialized form of motorsport - and put it on a path to much greater relevance among competitors, fans and sponsors, by upgrading our engine technology. And along the way, we can lower point-of-purchase costs as well as upkeep, and increaase duty cycles. Our only other realistic choice is to slowly watch Midgets evolve into a really cool form of vintage racing.
