PDA events are well-run and very friendly. I attended one at Lime Rock earlier this year and I had signed up for Pocono but had to cancel because of ViperDays in Virginia next weekend.
Chris Barone from the NJ VCA rents the Pocono track from time to time and I drove the North Course with his group earlier this year.
I'll be with PDA on Oct. 13th for two days at the Pocono East and North Course, and then at Lime Rock on November 10th.
If you can travel, ViperDays is the best value for the most track time and instruction at great tracks.
Have fun at Pocono!
