I am from So. Calif. It was on my hit list and made it. The bad part is that there were not any Hudsons as the person that owns the Hudson musume passed away and all the cars are being sold. He use to put Hudsons on display there and go there.
I can definitely recommend a visit to the Ypsilanti Automotive Heritage Museum in Ypsilanti, Michigan. In addition to Hudsons, they have a great display of Kaiser Frazer vehicles as well as other interesting cars.
