I was NOT referring to the Porsche Club of America PCA.
PDA is the Performance Drivers Assn-and is a school type of group like Trackmasters. Anyone can run as long as you have a valid license, insurance, and meet their age requirements to sign the releases. The website tells all about it. Cost per day depends on the track and configuration. I think that one will find that $200 is not uncommon for up to 5 30 minute sessions. Trackmasters is a bit different as to run time for their open group, but still economical when you consider that you are gaining seat time, which is key to learning both the car and track.

Have fun-drive safely.
