PCA Palooza is actually a joint production of the Cimarron, Ozark, and White River regions. I've been going since 2009 and it is always a blast with great drives, excellent sponsor support, and of course great Porsche people. Definitely not to be missed if you can make the drive. Here's a link to the 2013 website

P.S. the next time you come up from the DFW area drop me a PM and we'll go hit AR23 aka "the Pig Trail" through the south end of the Ozark National Forest. Once of those "must drive" roads.
