| Day 4: 25th April, 2010: After a rainy, rough, cold night in Ottumwa, SE Iowa, our plan today is to head north into Wisconsin bound for Milwaukee. For those amongst you who know something about bass guitars, it's here we pick up a Rickenbacker 4004 Cheyenne. From Milwaukee, we'll be heading NW to Lake Superior and Duluth and to catch up with Rich and Bette Koivisto. Rich works as a Met Observer at Duluth Inl. Airport and is a keen weather buff. | |
