The AMA Vintage Days are one of two of the premier vintage motorcycle events in the United States. The other premier event is the Barber Vintage Fest in Leads, Alabama (near Birmingham), which runs only a few months away in October. The Barber Fest seems to get better every year. If I had to choose between the two it would be Barber. The place is immaculate and the Vintage Motorcycle Museum is worth the trip alone.
