Many classes are already full and vendor spaces are also selling at a quick rate, especially in “the big room” aka Commercial “A.” You can submit your registration now through the website www.mcacn.com or call (586) 549-5291. If you are considering entering your car, the organizers say that you submit your registration asap!
