When I was driving to Houghton I got off US-41 in Chassell and took Chassell-Painesdale Road to CR-102 and made a left on Sharon Street in Houghton and ate breakfast at McDonald's. Then proceeded to cross the Portage Lift Bridge into Hancock and followed US-41 the rest of the way to it's northern terminus. Turned around and took M-26 along the lakeshore back to Phoenix then US-41 back to Houghton.
It seemed like it took a long time to get up to Copper Harbor though because I stayed in Norway which is about a three hour drive or so. Like I said before I wish I had stayed in Houghton.
