Now would be the time to start planning!! Pick a date and stick to it. Doesn't have to be anything big- The MACG started in a Walmart parking lot, with 4 cars in attendence! Now it the largest gathering of these cars and their owners, in the world!!
If you need any advice, please post! I would be happy to help, and I'm sure some of the more experienced car show planners we have on this forum, would be happy to give you all the advice you need!
