There are lakes in the Hayward area, Minocqua area, Tomahawk, Eagle River and of course Winnebago and the Madison Area.
I would pick a couple of areas, and then get info from the Chamber of Commerce for each town you want to try.
They would be able to give you the name / phone # of resorts in the area, as well as bait shops.
Make some phone calls and maybe even a road trip to check things out.
I would not keep my shack on the lake until I have been going there a couple of years.
Hope this helps,
