S&S Museum and Factory Tour/Viola, Wisconsin
After the Museum tour, I also took the Viola factory tour. This was one of the best tours of any type I have ever taken. The tour guide showed how S&S will make a engine block out of two halves of billet aluminum. We went in the factory, engineers offices, R&D, test cells and everywhere in between. On Sunday I took the La Crosse S&S factory tour which was also very impressive.
If you are ever in the area, call S&S and they may set up a tour for you. The Museum is only 10 miles from the Great River Road Rally and some of the best roads in the Midwest.
