There's a chance I may be camping at Nelson Dewey State Park along and above the Mississippi River near Cassville, Wisconsin this weekend. Most likely for Oct. 16, although not a "for sure" at this point. I was just checking and it appears the Cassville car ferry across the Mississippi will be operating through Nov. 1 if there's no drastic weather. It is located south of Guttenberg on the Iowa side http://www.cassville.org/rates%20and%20schedule.htm
This area is also not far from the park: http://dnr.wi.gov/org/land/er/sna/index.asp?SNA=337
Drop a line if this is of interest... as noted, it's a "maybe" at this point. Thanks!
