Anybody going? I'm seriously considering it. I go every year but have not yet done so with my T.
Just be forewarned, if you've never been, that 99.9% of the cars there are hot rods, rat rods, street machines, etc. with very, very few stock old cars. It gets very loud and moves exceedingly slow. There are a couple of T related events going on,though, in honor of Henry Ford's 150th birthday.
I did it last year with my T but not again, too many people showing off and peeling rubber for my comfort zone.
