you need to visit the Barber Vintage museum at Barber Motorsports park outside Birmingham AL.
They have 400 bikes on display, 600 more restored in storage and 200 yet to be restored. They do all the restorations in house and rotate bikes every week. An amazing place!
Was there 2 years ago. Definitely a place to see if your around there. The display of bikes is unreal and the building and grounds are something too see also. They were doing a Porsche driving school the day I was there pretty neat to watch.
