I have been to Green bay several times, both in the Winter and Summer. Warm weather is best. Not an impressive town, reminds me of South Bend but the Stadium is spectacular.
Wisconsin is such a beautiful place to visit though the lake coast doesn't come close to comparing to the Western shores of Michigan.
Madison is a fun town. Really beautiful.
I get to Wisconsin almost yearly for architectural tours all around the state. Home of Frank Lloyd Lincoln Wright. His residence Taliesin sits in the Wyoming valley along the Wisconsin river. Utterly beautiful. Much like PA but no real mountains to speak of.
North of Green Bay is wine and fishing country. At the very tip of the peninsula is a tiny state park called Rock Island. The place is full of snakes(none dangerous) but they are all over the trails. It is only accessible by boat and is a Summer camping destination because of the cool temperatures.
