Well, this one is simple.  Look at the map and go where the snow is.  That would not be anywhere around Duluth.  In the immediate Duluth area the trails are virtually bare and the warm weather coming on Friday won’t help.  Head north or head south but be aware if heading North that the John Beargrease Sled Dog Marathon will be on the North Shore State Trail from the 28th  to the 31st and snowmobiling, although still allowed, is not recommended on that particular trail.
