I was just wondering if there were any nice "farmy" areas with a good bed and breakfast, but also near the great lakes, like within one hour's drive.
Plymouth is a small town out in the country, but near the Lake. Door county, a peninsula out on the Lake, would be a good bet too.
Here is a link that might be useful: Plymouth B&Bs
If you look on the map there is an island just off the end of Door county. That's Washington Island. Cann't get much closer to the lake. House on the Rocks is another nice place if your family is a little older. The Dells are neat too.
Pretty much the entire southern half of Wisconsin is "farmy," but here in Dane County, some of the most interesting scenery lies in the hills and valleys around Mount Horeb, only about 15 miles west of Madison. Cambridge, Wisconsin, about 15 miles east of Madison, has a large pottery factory & sales outlet. Madison itself has the Saturday Farmer's Market, located on the Capital Square, where you can actually talk to the farmers who raised the animals/grew the vegetables. Lake Michigan is 70 miles to the east. For the full effect of Lake Superior, I would suggest a trip to the Keweenaw peninsula, through Eagle Harbor & Copper Harbor.
