I'm from SE WISCONSIN and would like to explore the US PARKS in NORTHERN WISCONSIN. This will be my first expedition thru the US PARKS, is there any good routes/maps to use? I have camped at many of the STATE parks the past four years, but want like to explore the US PARKS SYSTEM this summer for week-end trips (3 day). Any help will be accepted. I would like to plan a trip, May 10-12 starting around Mountain, WI.......
