Here's a direct link to the Entry List
From my local SCCA region, I know Kriz talked to me about attending both the Pro & NT in Blytheville. He's a solid driver and was in the last trophy spot at the Dixie NT behind Cy and Corey.
Personally, I'd go ahead and sign up Colin. I'm sure many will be moved to register when they see the current National Champ signed up for the class.
