Todd, I have raced PCA events. Even the one at Fontana only had a few 944's. One of them had only me. It was lonely out there and not much fun. I am tired of Time Trialing when I want to be racing.
My suggestion, if you are going to tow to California, is to race with Ken, Greg and the rest in a NASA event. You will have a good car count, play with a growing 944 crew, great trophies and a great bunch to hang with. After all, at least 3 are with Pixar so you never know what they will come up with.
I plan on racing with them yet again next year and wouldn't miss any event with them that I can fit into the schedule.
My 2 cents worth.
