We toured the museum a few days ago. It's a must see! They are building a new facility to house even more bikes & cars. Lots of historical machines there. May go back in April to the Honda Indy event. Anyone been to the races there? Suggestions?
I have been about 4 or 5 times and I never get sick of the place. I think the best time to go is in October during the Vintage Festival. It really is a cool event and you'll also be able to see some spectacular vintage bike races.
