Just a guess as I've never been there, but I have the perception that the site isn't so large that we all won't see one another once we get there. Combine that with cell phones, and we should be able to meet up.
My tentative plan for the Holiday traffic scenario is to run something like 23 or 57 or 20 etc. east bound, which offers a long series of back roads, then probably run the MA pike back West after the show. That reminds me - I should order a motorcycle specific EZ Pass. They apparently don't like me using the car's transponder, even though that gives them an extra dollar or whatever.
