There is no doubt that if you are a motorcycle aficionado, this place will make your head spin. Bikes upon bikes upon bikes of every make, model, and year. Racing, touring, dirt, hill climb, there all there along with a ton of memorabilia.
However, the museum is unorganized. Most bikes lack any description about uniqueness, history, age, etc. So to a casual observer, it seems like just a hodgepodge of motorcycles. Additionally, the displays are dusty and appear neglected.
Of course the bulk of the items are Harley's. And I think all the bikes are American made which is okay by me.
If you are into motorcycles you won't want to leave. If your interest is casual, 1 to 2 hours will be more than enough time to peruse the collection.
