Every year, the Viking Chapter of the Antique Motorcycle Club of America (AMCA) puts on an vintage motorcycle show at the State Fairgrounds in St. Paul. I went in 2008 & 2009. The show this year is June 11-12th, 2010.
Last year I was there on 6/13/09. Here's my Road King at the Fairgrounds that day:
Not only are there about 150 bikes on display, you may see a few ridden out behind the building. There's also a swap meet out back too. Almost as impressive as the bikes on display are the bikes in the parking lot.
Here a just a few of the bikes I saw at the show in 2009.
