Indoor dragstrip would be cool, I agree with the above comment about the shut down area being outside, you would have to pit everyone outside so why not have the shut down area going out of the building. The building would keep the 1/8 or 1/4 mile away from the rain, only thing you would have to do then is dry the shutdown area..

What I think is even a better idea, would be to make a cover that extends from one guardrail to the other during rain or even when track is not in use. You could do it just over the racing surface or make it the entire length of the track just before the turn offs. I wouldn't think it would be hard to design, just the $$$ to design and for the tracks to purchase it..

Either way would cost $$$ and right now not sure anyone has the $$$ to do it.
