Every year our church has a 4th of July party where we have 1000 people show up. We have a little car show and it has now been handed to me. What is the best way to get cars to show up at this? Usually there is about 20 cars but this is a cool community event where we give away hot dogs cookies chips popcorn etc. All for free. There are no prizes for your car just good clean fun. Ant suggestions are welcome. TIA. Martin
