WISCONSIN – June 3-8, 2012
Wisconsin is a beautiful, scenic state with terrific destinations. The start end/point will be in the Milwaukee area. One of our stops will be the Wisconsin Automotive Museum in Hartford, which has over 100 cars on display. We will be visiting the staff of Old Cars Weekly at their headquarters in Iola. House On The Rock is an amazing creation that came from one man’s boundless imagination. It is a unique architectural marvel that could be described as part house, part museum and part circus. The Wisconsin Dells is an area of lakes and unique rock formations. Door County is all coastline dotted with lighthouses. We will stop for some cheese, and as usual there will be something for everyone.*
