Some of it is open, correct? My roomie just did a "Ride for Cancer" or something along those lines, and Im almost positive that it was held there. If so, Ill have him chime in and let you know.
He did talk about the surface not being all that grippy cause its new, but he did love it. I believe MotoGP is looking into expanding to that track as well. Ive heard they want to drop Laguna because the corkscrew is too iffy for them (IIRC they want Laguna to shave down the entrance some so its safe for the riders).
Anyway, Ill have him post.
