I happen to love the Seney swamps. Most of the wolves I've seen up here have been while traveling that stretch, especially in the wee hours. The entire shoreline of the UP is stunning so IDK how to choose there, either. I do prefer the western half overall (mostly because of the ruggedness), but LOVE Munising to Paradise N of 28.
The whole area is a remote northern wilderness and I love every minute of the 6 month winter, too.
