The largest motorcycle collection in the world. A beautiful, purpose-built museum to house it, including a race track to run on and workshop to restore that which is ailing. Every bike on display, around 800 of them, is fully restored and running.
The Barber Museum also holds the largest Lotus collection in the world, although they are still waiting for certification before they can say that officially.
I visited as part of the second half of my Southern States Tour. Spending an entire day at the museum, with a break for lunch, was a joy!
