another suggestion..... I would try to hit M66 as early (meant as soon as you could get to it) as possible and ride that up.... goes on the western side of the state, but not as much touristy stuff....hit the bridge and do whatever, and take US23 back south. I would avoid 75 as much as possible. I'm leaving tomorrow after work to head to Moorestown for the Jack Pine Enduro. It is the second oldest, if not the oldest, endure in the US! Started in 1923. Been doing that since mid 70's....racing it, working it, check points and road crossings. My route up is M66... it is a nice, pretty leisurely ride up. two lane, good road surfaces, small towns to go thru, and not really heavy on traffic.
Enjoy your trip through our state....it truly is a beautiful state!!!

 

Thanks guys.

 

I just got back from a 4 day trip to the U.P. If you have any questions, let me know and I'll try to answer them. You can pm me if you want.

 

Thanks. I might just do that.

 

The wife and I just spent a week touring the UP. Stayed with Patty and Andy. Great people for sure.
