There are Hmong people in Plover but yes not much to do. In Wausau, not much to do either. Visit Rib Mountain in Wausau, nice and beautiful place. Oshkosh & Green Bay not much to do either. If you go north of Green bay is Door County and that's a popular destination. WI is known for beautiful State Park, nature, and there's one near every county. Maybe visit the state park or just enjoy the nature trails
