Mopar Max event in NE Iowa

So how big is this show? Worth a 4 hour drive one way?
That's a stretch. The car show is 30-40 with trophies. Same with the racers. 30 -40 I would estimate. Swap meet being end of season has a couple dozen vendors but we are trying to make it a bigger event. The more that shows the better the show. If you're a racer I remember hearing they will pay a couple thousand $$$'s to win this year. We are local but are planning to come Saturday and camp over night. Here's a link to the 2015 event I had saved. I posted quite a few photos that you can view by clicking on the photo name.
