Orlando and West Palm Beach

Probably the biggest Mopar show in Florida is the show at the Don Gartlits Museum of Drag Racing in Ocala. Its always on the first Saturday in November, so it looks like you'll miss it. I believe its November 4th this year.
Here are pictures I took at last year's show.

Not a Mopar show but the weekly Saturday afternoon/evening cruise in at Old Towne Kissimmee
is always worth attending.
Here are pictures I took one Saturday last November.
