For mustangers, you'd need to be a member of MOCA and put your name on the list at their club meetings. The quota is full for this year as that process started in May. There is a waiting list, but you need to be a MOCA member. Other than that, most of the clubs are vehicle related e.g. Small fords, Model T, falcon GT etc. Having said that, there is a general parking area for those Fords not affiliated with a club from memory. And then there is general parking. It's always a great day!
