Anyone planning on going? Basically a spin off series of LeMons, little bit different rules (less cheaty).

I believe the entry deadline should read April 22nd, and I don’t think any ChumpCar race has been in jeopardy of being sold out. So if a build takes longer than expected you probably can still get in.
