"Up north" joke that summer is July 17th and wrecks the snowmobiling :-)
By all means, visit Oneida. Seems to me the prettiest part of the state, or one of them. The geography is distinct (at least to my eye) -- the gentlest of hills, shallow, sandy lakes. Water everywhere. There's a swamp between Three Lakes and Monaco. As nearly as I can dope it, the Eagle River and Wolf River both rise there, no more than a few miles apart. The former flows into the Wisconsin, and on to the Gulf of Mexico. The latter flows into the Fox and Green Bay, and thence to the Atlantic. Actually, it's a triple divide; some Lakeland waters flow into Lake Superior.
But, no pheasants :-)
