Seems as tho BoHo is on most of the MI SBF members list of "Want to Go" but can't recall if any of us actually have. So, I've been up there in the fall for photography but I've ever been up that way in winter. Roads in the UP are mostly winding two lane blacktop. And that region can get up to 10-12 ft. of snow in a season, so be prepared. (...you'll need the 4x4!)
....if you do go, post it up in the MI regional forum! We all want to hear from someone with first hand experience with the place!
