I've done the MKM race before. It's fun. I didn't know they had one in March though. That's way too early. I've done the Pony Express race of theirs. The SSC car has done races like this before and failed miserably every time. (before they were at the Silver State Classic Challenge http://www.sscc.us
) Doesn't surprise me that they didn't make it again.
Nothing quite like the experience of legal high-speed racing on public highways.
