For those people that do not want to race can just go park together like the "show car area" that you see in let's say, Nopi events.

I really do think that making a meet at a track would be your best bet and may attract even MORE people. You can even set it up that people race each other "street racing" or "Pinks" style where they line up and go off of the person's hands lol (having trouble describing it) and don't show time.

Just try to keep in mind all the benefits to this like almost Unlimited parking and if you throw an event yourself i'm sure you will make money.
