PCD is such an awesome experience, you definitely made the right decision to delay delivery. The only thing better is to do ED then PCD, but that would push the production date out further.
I've always driven straight home from the Performance Center. Pretty boring drive, but still fun until you hit traffic. I guess you can take Blue Ridge Parkway/Skyline Drive since its pretty scenic and fun when there's no cops on the road... But, there's always cops
