Autox for Cincy Sunday event?

[sirocco@telocity.com (Randy B)]

Yeah, that kind of makes sense........but I'm still not totally convinced

It's got to be a compromise between the two, traction and acceleration.

What day is the autoX this month?
I am a little short on cash this month but would like to head down there 
this spring :)
