Stars101, I live in WI, and will say Door County is very nice and famous for fish boils, also the WI Dells, has a great boat ride. If you get North toward the boundary waters, it is our favorite to go to Duluth and camp up on the way to Grand Marais, it's called the North Shore. It is some of the best biking and hiking we know of. There are beautiful water falls and cliffs. It is what I think Maine would be like and that's why I want to go there. Nature and fresh air is what we love. DW loves reading books about Maine and the lobster fishing stories, so we need to go there.
Thanks for all the comments.
